Cool Idea, and nice project! Controlling both players was a bit of a mind-bender for me, but was fun and could be neat to play with two people. Good use of the theme too!
The song you used is "Phantasy" by AGST, it's a really groovy tune, and it fit the "quirky" vibe of your game well. It was maybe a little distracting though as well, you could maybe try using some music with a similar vibe, but less "in-your-face".
all in all a really cool and unique submission. Well done!
