Well, that's definetely something. Good job on at least "finishing" and submitting it. It's actually has a pretty catchy gameplay loop of endless upgrades. For starteds, I wish background music would loop :D
Jump sound effect is spot on, fits very well. Perhaps you should've gone with more minimalistic approach to graphics, less complicated forms to be able to animate them at least a little.
Also one of the enemies landed on my head and I was unable to do anything to him :(
Keep on keeping on, the core of the game is there and it's fun!
