Hey! It's a nice concept! OK, the game is impossible and didn't even know if you can finish it x) but still funny! Here is one suggestion :
- The switch button to change the color of your character and make the room "doodled" is an interesting concept but not enough useful : Maybe you should add 2 different spikes (normal and white doodle) and the player is not taking damage if he get hit by the spikes of his form, ex : (doodle spikes doesn't hit doodle player).
Otherwise the game is nearly finish, keep doing jams and try to finish your project next time :)
