Cool entry !
I like the originality of you powerup system, balancing something like letting player draw their own platforms can be pretty hard to do with how exploitable it can be :p
and the bullet acceleration mechanic is really quite unique i gotta say
Spritework and animations are really well made.
Music is nice, just too bad there are no sound effects to complement the package :(
If i had to nitpick i'd say the jumps can be a bit too floaty at times especially when you have to be precise.
Other than that it's solid, you guys did great :)
