This competes with "Flip" to be my favorite your game. 51 minutes played. My record: 1427 meters
1) Scroll works "smoothly" which is bad at the game where switching between "Pixelate" and "Sword" has to be close to immediate. Even better would be just to assign sword and gun to some keys on the keyboard.
2) Sometimes after going through the whole area the character falls into the abyss not reaching the next area
3) Two enemies ahead almost certainly means death (because of note #1), but even with that fixed, I think it's a good idea either to give player some invincibility period or to make enemy die on collision (or both).
As with "Flip" I would really like to see more completed/refined version of this game.
