"Reach Atlas without dying"

From a fresh profile, beat the game (by clearing level 5-6: "atlas") without ever dying or resetting to the last checkpoint. This doesn't have to be done in a single play session.

The moment you die or reset to the last checkpoint, the game saves that information to your profile, permanently preventing you from being able to earn the achievement on it. It doesn't matter if you quit the level immediately after your mistake, or replay the level without making one; you're screwed, and will have to start the game again from a fresh profile.

Because the game doesn't save information to your profile when you select "Back To Level Selection", select "Quit To Desktop", or simply close the game with something like Alt+F4, you can safely use any of these options to save yourself from dying if you happen to notice in time, or to save yourself from a softlock. You will have to replay the level afterwards, but that's better than replaying the whole game. This trick is particularly helpful if you catch yourself falling to your death, but it won't save you from being unexpectedly crushed to death or killed by purple goo. That means purple goo, moving platforms, Force Cubes, and even doors are the real threats to a "Worthy" run, so be careful around those!

As with any deathless challenge in a video game, it helps to be familiar with all the levels before attempting the real thing, especially those closest to the end. In particular, I recommend practicing levels 4-4: "fracture" and 5-5: "crossing". If you're having trouble finding a safe and consistent route through a level or don't want to try to, it helps to search for videos of the level online.

Consider attempting "Worthy" only after achieving 100% on your first profile (which you have to do anyway for the "100%" achievement) to familiarize yourself with all the levels beforehand and to remove any need to find tokens in the "Worthy" run itself. It's also a good idea to try earning "Dry Feet" in the same run as "Worthy" if you don't have either achievement.

I recommend playing on version 1.2.1, the current version, instead of version 1.1.3a. It has fewer bugs, and to me it seems to have better performance. It may even be impossible to use the intended method to earn "Worthy" on version 1.1.3a due to the existence of the bugged method.

On version 1.1.3a, switch from a profile you've beaten the game on to a newly created profile. That's it.

"Keep your feet dry until the Atlas"

From a fresh profile, beat the game (by clearing level 5-6: "atlas") without ever stepping in water. Neither waterfalls nor snow count as water; you'll know you've stepped in water if you hear a splash sound. This doesn't have to be done in a single play session.

The moment you first step in water, the game saves that information to your profile, permanently preventing you from being able to earn the achievement on it. It doesn't matter if you quit the level immediately after your mistake, or replay the level without making one; you're screwed, and will have to start the game again from a fresh profile.

Because the game doesn't save information to your profile when you select "Back To Level Selection", select "Quit To Desktop", or simply close the game with something like Alt+F4, you can safely use any of these options to save yourself from landing in water if you happen to notice in time. You will have to replay the level afterwards, but that's better than replaying the whole game.

It helps to be familiar with all the levels that contain water before attempting the real thing, especially those closest to the end.

These are the levels that contain water:
• 1-1: "calling"
  
• 1-5: "courtyard"
  
• 1-6: "discovery"
  
• 4-1: "air estate"
  
• 4-3: "conservatory"
  
• 5-1: "headwaters"
  
• 5-2: "library"
  
• 5-3: "palace"
  
• 5-4: "basin"
  
• 5-5: "crossing"

In particular, I recommend practicing levels 5-3: "palace", 5-4: "basin", and 5-5: "crossing". Clearing level 5-4: "basin" without getting your feet wet requires an especially difficult jump near the beginning of the level. This video by 100% Hippo shows how it's done: https://youtu.be/iJm9wWjNpJg If you're having trouble finding a safe and consistent route through a level or don't want to try to, it helps to search for videos of the level online like this one.

Consider attempting "Dry Feet" only after achieving 100% on your first profile (which you have to do anyway for the "100%" achievement) to familiarize yourself with all the levels beforehand and to remove any need to find tokens in the "Dry Feet" run itself. It's also a good idea to try earning "Worthy" in the same run as "Dry Feet" if you don't have either achievement.

I recommend playing on version 1.2.1, the current version, instead of version 1.1.3a. It has fewer bugs, and to me it seems to have better performance.

There is no bugged method for earning "Dry Feet", so good luck!

You can switch between versions 1.2.1 and 1.1.3a at any time in the game's properties on Steam. Note that the "Rage Quit" achievement can only be earned on version 1.1.3a, so you can't complete the game without switching versions.

To switch versions, right-click the game in your Steam library, click "Properties...", then click "BETAS" on the left. In the first drop-down list, select "None" to switch to version 1.2.1, or "1.1.3a - 1.1.3a" to switch to version 1.1.3a.

It's possible to trivialize earning these achievements by manipulating save files from outside the game, but this is cheating. Certain achievement-tracking sites and achievement-hunting groups would not allow this. Please use the other methods explained in this guide.
