One of the first challenges mentioned in the forums. (It didn't have a name so I'm going with this.) A user named Mei suggested beating the game without breaking any clothes, and uploading the images. This original idea later ended up being put into the game as Gentleman Mode.

However! Any chump can do it that way, so instead we're going to turn it up to the extreeeeme! Keep in mind that this challenge was before the other difficulties were even in the game yet, so we'll be sticking to Normal difficulty. And obviously, one-hand mode is unviable for this. (Special note: Due to clothing damage not showing up on the screenshot screen there's no simple way to actually prove you did 0 damage to clothes so it's an honours system)

The rules are as follows:

• Normal difficulty. (4 lives)
  
• Slow Time is allowed only.
  
• Deaths are allowed.
  
• Collecting any point stars is an immediate restart.
  
• Causing even a single point of damage to any clothing (Making the hitbox appear) requires immediate restarting.
  
• Clothing without visible hitboxes (Bracelets/Sunglasses for example) can be shot but must not be blown up.

Difficulty rating: ★★★★

Tips for this challenge:

Get used to restarting, bucko. >:D The difficulty in this challenge doesn't come so much from risk of death because you won't be able to shoot the majority of enemies on a level, but from being tempted to shoot and clipping a clothing hitbox, or shooting to clear enemies and having a point star home in on you. Remember that bombs and side weapons (Laser, missile) will NOT damage clothing, and that lasers especially are VITAL for being able to shoot bosses on most levels due to their aiming. More than anything else, this challenge is about patience; pick your shots carefully and always make sure to be firing with laser from as far away from a hitbox as possible.

Hardest part: Nikita's stage. It's the longest of the stages, and there are very few safe places to shoot without clipping a hitbox. Prepare to spend 10 minutes slowly whittling away at the boss with lasers.

My personal challenge, and the reason I made this guide in the first place. (Totally not to upload lewd images with the nude patch I was testing so people won't see in Activity or anything >>) This is the challenge for the big boys; beating the game with no deaths, 5 stars, full 100% clothing damage, Fox only, Final Destination! >:O

Are you a bad enough dude to flawlessly defeat every stage?

The rules are as follows:

• Hard difficulty. (2 lives)
  
• Bombs allowed only.
  
• Death means an immediate stage restart.
  
• Failing to destroy all clothing means a restart.
  
• Failing to achieve 5 star rank on level completion means a restart.

Difficulty rating: ★★★

Tips for this challenge:

Knowledge of the enemy layouts and stage progression is what matters most. Now that hard mode doesn't double the stage's progression speed, you can VERY easily get through with no deaths all the way up to the bosses. With a certain exception or two of course. There are two secret ways to increase your score exponentially; I could tell you, but I like being at the top so you figure it out! >:O

Hardest part: Technically two hardest parts. Misako's stage is still a bastard at times if you get unlucky with what enemy layout you get and have everything ever spawning in at the same time with bullets and explosions everywhere... But the boss in Remi's stage (You know the one) is actually a genuine threat by dint of murdering your runs on that stage with its stupid laser attack that will only miss if you haul ass across the screen, and the laser ball which falls down and turns around twice, leaving a trail and having a tendency to suddenly take you roughly from below.

Your bog standard "I'm a casual but I want to join in too" challenge. Nah, I'm just messing with you. This is a deceptively hard run where you clear the game without any points and not shooting any enemies except for the boss at the end of the level. There's not really much more to it, but it makes for great practice for learning level layouts as you're watching enemy patterns more intensely than if you were just moving side to side and shooting all the time as normal.

Note that while it sounds easy because all you have to do is dodge, there will be a lot of enemies onscreen shooting at you because of it.

The rules are as follows:

• Any difficulty is allowed.
  
• Slow motion allowed only.
  
• Deaths are allowed.
  
• Clothing destruction is allowed.
  
• The only enemy you can destroy is the boss.

Difficulty rating: ★★ to ★★★★★ (Depending on difficulty and level)

Tips for this challenge:

There isn't much advice apart from "Learn the levels". Once you have an idea on most of the enemy spawns in a level, it'll fall easily, at least on Easy or Normal. Each enemy has a fairly straightforward pattern of attack, but with so many at once you'll either learn to get good at streaming (Slowly nudging sideways to avoid shots aimed at where you were) or dying.

Hardest part: Misako's stage. You've seen how silly intense her stage gets in at that specific point where the miniboss usually appears? Imagine that, but with all the enemies alive and shooting at you.

No, not the one from Rainbow. This challenge should be familiar to anyone who's tried to play Call of Duty or such with maximum aim sensitivity. See that "Bike speed" dial? Crank it up to maximum. Now beat all the levels like that with the keyboard. :D

The rules are as follows:

• Any difficulty is allowed.
  
• Mouse and One Hand mode are forbidden.
  
• Only Speed Glitch is allowed. Have fun with that.
  
• Deaths are allowed.
  
• Clothing destruction is allowed.

Difficulty rating: ★ to ★★★★★ (Depending on difficulty and level)

Tips for this challenge:

To be honest this won't be that hard. Sure, you have basically no way to safely avoid anything and you'll be sliding more than Luigi in Super Mario Bros 2, but at least it'll be funny. If you keep moving wildly back and forth while shooting and blow up most of the enemies, you can probably just brute force a win even with a few deaths. Have fun with the bosses.

Hardest part: Any boss fight. Shooting them will be hard enough, but on top of having to dodge carefully to avoid getting hit? It'll be a good laugh. For the boss. Not for you. >>

Everyone who I confirm has passed my Stardust Challenge, will be remembered forever and ever here as a legend! :3 And for fun, I'll even make a little leaderboard with each girl's score. Get first place and you'll get spiffy stars around your name! :D

Submitting proof is easy enough: Either upload screenshots of your uh... screenshot screen, and then tell me so I can check your profile and confirm it, or upload it on somewhere like Imgur or something. Not sure what the screenshot screen is? Look further down below in the guide for my pictures.

The screenshot screen will show the difficulty, your score and star ranking, and obviously if you blew up all the clothes or not. It won't show if you died or used slow motion, so that's an honour system thing. Also Sumeru Sayru and Arouse-chan are not counted as they have no scoring. So you should have as of right now, 11 girls to defeat and submit.

Note: Updating even one person's results takes a solid 15+ minutes, including having to tot up all the points for the overall scores and stuff on a calculator. So expect to wait a few hours/days depending on how bothered I can be and how much I have to change. -3-

Just a mini-section to show proof I completed it myself, and also to show people how to submit their scores/completion of it.

All you have to do is beat the girl, and click the "Take picture/screenshot" button instead of going back to the menu. Then press whatever button your steam screenshot key is mapped to on that screen, and you're good. :3 Show me that screen and I'll confirm that you beat that girl. Alternately if you fudged it up and didn't screenshot it with steam, you could upload that game screenshot to Imgur or some other picture host place and link me to that.
