Game is cute. I like the art and the gameplay.But there are a few problems
1) The music stop after a while(have it when the music finishes start it again)
2) There are no sound effects(Add some jumping and shooting effects)
Some things you can add are, looping music, sound effects, and better animations(the spring bouncing the player or something like that)
Over all, I liked the game. it was fun. these are just some problems i had with it. Take care.
If you want you can check out some of my games if you want.there pretty bad.
