Really nice art you made! I like how you use engine to animate player (squash effect).
Moving around and shooting feels right and it's fun itself, that is sing of good design!
I like spore mechanic and how you used engine to simulate gravitation, that's open a lot of possibilities :D
For sure you have some cool core mechanic that could be scaled to something bigger. Level list with timing is really nice polishment!
Unfortunately I stuck on level 2, I did try few times in full screen but still couldn't find the missing place. Even I discovered that you cannot fall down (made my day) :D
Great job and congratulations on your submission!
