That was a fun game and a really good idea. idk if it was just my browser but I don't think I got the full experience. Every time I changed color it bounced me to the bottom of the page, if you used full screen I saw half the bottom screen and half of the title screen. I also kept getting an unknown "Youtube error: 5" every few seconds.

I saw all your challenges but I didn't see how the following matched:
2bit color: since black and different shades of the same color count in 2bit I counted at least 10 different colors used.

Never stop: You said flash movements but your player can and does stop movement.

Spin me around: I didn't really see anything rotating, so I don't think it can be called a primary mechanic

Bodyguard: I think you may have misunderstood this one. Your player can die, his flash trail that he leaves behind him is invulnerable. If you would have made the flash trail the only way he could die, but your character invulnerable I think you could have used this challenge.

Disinformation: Not sure you could say this game is full of lies and deciet

I loved the game mechanics and special abilities.

Boing! I didn't see anything actually bouncing off of anything else.

Gotta Go: There was no information given about a level change after 10 seconds, and part of the fun was to see how long you could last.

I know I tore this apart but this was a really neat game and I would love to play it more if you ever decided to continue developing it. Keep it up!
