There are a total of 35 achievements for this game that will be broken into the following groups:

• Special Completion Achievements
  
• A++ Achievements
  
• Misc. Mid-Level Achievements
  
• General Completion Achievements
  
  
  About half of these achievements can be done fairly easily but the other half are going to be harder to do. If desired some of these can be grouped together to make it quicker.

The achievements in this second will require you to do something during the level prior to finishing.

• You Jelly - Finish a story level with both sides covered in Jam.
  The Jam is located in the mason jars scattered around the levels. In this example I chose the first level which has a jar right at the beginning. Simply break the jar and then begin to flip the bread onto the jam and slightly move around. This will take some time to completely cover the side but when it's done it should look like:
  
  
  
  Repeat the process for the second side and proceed to finish the level.
  
  
• The Walking Bread - Finish a story level with less than 1% edibility.
  I found the easiest method for doing this was to first completely toast the bread and get each side to 100%+. Once you are able to end the level land on the floor. With the right timing you can end the level at exactly 1%. It may take a few tries but is easily doable. There are some other areas you can land to start to damage you such as in ants or in water. For precision you can try tapping a wall that has mold.
  
  
• Picky Eater - Use more than one heat source to toast yourself in a single story run.
  This can be done on levels that have more than one heat source which I believe is most levels. I found the easiest level was the first level. There are 4 options for potential heating: The burner, toaster, oven, and the rocket. I personally chose the burner and the toaster because they seem to be the two easiest in this level. First turn the buner on by using the nobs off to the side of the oven. Then try to get an even toast for both sides (Equal percentages). Once you have it even cooked but not finished proceed to the toaster. Just pop yourself in and once you get 100% on both sides you can end the level and unlock the achievement.
  
  
  
  
• Fuel-Efficient - Finish a Zero Gravity level using less than 100 fuel.
  This one can be pretty easily done on most of the first few missions with a little practice and some luck. I believe that I unlocked this on the bedroom level but got close on a few others. Just have to find one that you're good at and keep trying. Try to use short bursts and take your time.
  
  
• Fresh Slice - Finish a story level with 100% edibility without using the Magic Marmalade.
  This achievement is rather difficult to do so you have to be extra careful. Again I found the kitchen to be the easiest for this because it has the fewest amount of prominent dangers although the Garden level could be done if you are skilled scaling walls. This may take several tries as you want to make sure to avoid anything that will lower your edibility. If you manage to make it to the heat source and still have 100% it's still not over. You need to make sure that the slice is cooked evenly and not burnt. This is why I found the burner and toaster to be the easiest method. Just flip off as soon as you hit 100% and then switch sides.
  
  
• Bunbreakable - Finish a Cheese Hunt level with 100% integrity.
  I found this one to be the most challenging. Even if you take your time and try to move slow you can occasionally get a random break that will force you to try over. Although for this one I went with the first level. As far as the order of cheese I found this to be the easiest: Jenga blocks, trash/stove, on top of freezer, top cupboards, and table. That seemed to be the easiest way to go and just use the walls for going up/down when you need to. Also try to shimmy left/right rather than flipping over when climbing. A lof of the time that I tried to flip over while climbing led to be partially breaking the cracker. If you choose to go this way just a couple of heads up that you should watch out for: one of the stove tops is on so be sure to go around it or turn it off, the jenga blocks cause a lot of issues, and knock the last cheese off of the jelly jar rather than climbing it. Also it will sometimes just randomly crack and cause you to restart but don't let that get to you, just keep trying and eventually you should get it.
  
  
  
  
• Bready for Anything - Finish a Story level using Magic Marmalade.
  To unlock the magic marmalade all you have to do is lose twice. One the third try there will be a glowing white object that once picked up gives you unlimited grip abd infinite life. This is what it will look like:
  
  
  
  Just flip the bread into it and finish the level.
  
  
• All Buttered Up - Finish a Story level with both sides covered in butter.
  This is exaclty like the Jam achievement except for this time you are going to cover yourself in butter which makes you slippery. On the kitchen level there is some butter on the starting table that can be used. Simply pull the cover off, or smash it, and begin to cover yourself. It's difficult to tell when you're completely covered but you should notice some shininess when light is put on it. On this picture you can see that half is buttered while the other half is not.
  
  
  
  Just like in the other achievement you need to completely cover both sides and then proceed to finish the level.

These are the most difficult achievements to get as they require you to score the highest possible ranking: an A++

If you're just trying to get the most achievements but don't care about 100% you can try to go for the A++ rank on one level but unless you're willing to spend a lot of time fighting for all of the A+ ranks, the all levels achievements are better off avoided.

• Turophile - Get an A++ on all Cheese Hunt levels.
  
• The Rye of the Tiger - Get an A++ on all Rampage levels.
  
• The Flour is Strong with this Bun - Get an A++ on a Zero Gravity level.
  
• The Final Buntier - Get an A++ on all Zero Gravity levels.
  
• The Best Around - Get an A++ on a Bagel Race level.
  
• Raconteur - Get an A++ on all Story levels.
  
• High Roller - Get an A++ on all Bagel levels.
  
• Cool Story, Dough - Get an A++ on a Story level.
  
• Always Baguetting Better - Get an A++ on a Rampage level.
  
• A Wedge Between Us - Get an A++ on a Cheese Hunt level.
  
  As far as a guide you need to be as quick as possible so practice launching yourself from place to place, moving quickly on the walls and tables. Try to find the quickest and easiest path. most of these levels can be done in 1-2 minutes so try to aim for a time around that. Cooking can also make a major difference in score so you may want to practice cooking and the best placement on the heating element. Sometimes it's best to stop a little before 100% because during the flip and other side you may get a few % change.
  
  CaptureRapture does an excellent job showing some different guides for getting A++ ranks on all of the levels. I recommend watching them to at least get an idea of a route to take that will be quick.
  
  

The achievements in this category require you to perform an action during the level but you do not have to finish the level. As a heads up for these you are going to want to grip items with the lock button rather than the typical ones used for moving.

• TV Dinner - Break the TV.
  
  This is pretty straight forward. On the lounge level one of the options for heating is the TV but it must be broken. To do this simply go to the shelf above it and then drop the bowling ball onto it.
  
  
  
  
• The Bread Baron - Stay airborne for over 5 seconds on any mode except Zero Gravity.
  
  I unlocked this achievement by accident by gripping a boken object and sort of having it glitch launch me into the air but there are other options that should give you pretty good air time. On the garden level outside if you launch yourself above the fence the wind will pick you up and take you a bit further.
  
  Notice: It seems that there is an easier method for unlocking this achivement as pointed out by The Dr. Notch Brony . It seems that all you have to do is start the bathroom level on rampage and wait for five seconds and the achievement should pop.
  
  
• Shadough of the Colossus - Climb atop the Garbage Truck in Story mode.
  
  The garage truck is the starting location on the very last mission. To unlock this achievement I found ti easiest to go off to the left side of the back and onto the cans. Once you're there wait for the grip to be all the way up and start your climb. It's fairly tall so you are going to want to be quick. Once you climb to the top you should get the achievement.
  
  
• Rye and Dry - Turn on the Hairdryer.
  
  Just like the TV in the lounge this is a heating option in the bathroom. It's even easier than the TV to turn on just have to press the button that is on it.
  
  
  
  
• Joy Rye-der - Start the car.
  
  This is one of the hardest ones to start in my opinion. First you have to choose how you want to get inside. You can break the glass on top or choose to go in through one of the side windows in the front. Once you're inside of the car make your way to the driver's seat. Go onto the steering wheel and make your way to the key. Simple grab the key and the car will start. Make sure to get the lower part of the key to be able to turn it.
  
  
  
  
• I am Dead - Become inedible.
  
  This is the easiest achievement by far, you'll probably just get it by accident so it doesn't need much explanation. If you want to get it easily just fall onto the ground and wait a few seconds.
  
  
• Doughny Hawk - Stand upright on the skateboard and ride it for 1 meter as the Wholemeal bread.
  
  This is going to take a little bit on maneuvering to get the board in a good spot. If you land horizontally onto the board and lock in with one of the sides you can adjust the angle the board is going in. You should eventually get it into an angle like this:
  
  
  
  Then you want to get into position, towards the center of the board, as I found that to be were the achievement registers (unlike shown here). Then get the board moving forward and begin to flip the bread horizontally.
  
  
  
  This is going to take a few tries but is fairly easy if you have enough runway for the board.
  
  
• Bunfortunate - Spill the salt.
  This can be done on the very first kitchen level, right at the beginning. Simply knock over the right shaker and you've unlocked it.
  
  
  
  
• Bagel Space Program - Launch the rocket.
  The rocket can be found on the Kitchen level and is at the very top of the first kitchen counter (the one with all of the ants). The way that I got up to the top was first climbing the refrigerator and the scaling the wall up to the top. From here all you have to do is lock on the rocket and make sure you hit the button on the side, or have it hit the floor.
  
  
  
  
• “Party’s Over!” - Start the Lawnmower.
  
  Starting the lawnmower can be tricky if you choose to climb up the handle but I found it easier to scale the wall behind it and move onto the top. There is a big blue button that just needs to be triggered and once it's done hold on because the mower will speed off.
  
  
  
  
• “Grooovy!” - Start the Chainsaw.
  
  The chainsaw is found in the garage level just like the lawnmower and is on top of the fridge.On the one side you will see the pull start. Simple lock on to that and fall off the side of the fridge and it will start right up.
  
  
  
  

These can easily be obtained without having too many issues and will be unlocked as you complete the other achievements.

There is really no need for a guide for these achievements, just take it one level at a time and these can be easily done. Some of the harder levels just take some time and practice and they'll be done.

• The End if Rye - Complete all Story levels.
  
• Rye Hard - Complete all Rampage levels.
  
• One Giant Leap for Naankind - Complete all Zero Gravity levels.
  
• Good All-Rounder - Complete all Bagel Race levels.
  
• Brie-lliant - Complete all Cheese Hunt levels.
  
• Bread Leader - Take out the Starch Destroyer
  
  Taking out the starch destroyer is done by first destroying the 3 main orbs. There are two orbs at the top and one on the bottom. Taking them out with everything can be rather difficult, so I recommend taking out at least a few of the guns on the ship. Taking out enemy aircrafts is more difficult that it's worth in my opinion, doing a few maneuvers is enough to dodge their attacks. After taking out all 3 orbs you can have launch yourself into the toaster. This can be found on the center of the starch destroyer. The whole thing is laid out as an ironing board and an iron. The toaster is located on the button of the iron.
  
  
  
  
  
  
  
  
  
  

Overall about 50% of these achievements are pretty straight forward and easy to get but the rest of them will require some effort. The last 5 A++ achievements are going to take some time but can be done with enough effort and a bit of luck.

Special thanks to CaptureRapture for the A++ guides.
