Seeing that you didn't make the art yourself and that you didn't check the copyright for the art you found online, this entry should be disqualified(at least for the compo, seeing you need to make everything solo from scratch).
Never use art/sound/whatever without knowing if you are allowed to use it. You are currently infringing copyright(it does not matter if you make money or not) and people can sue you for it when they find out that you used their art without their permission.
Other than using graphics that were copyrighted, this game was a bit weird in movement but it is fun to play. I featured this game in my LD27 compilation video series, if you'd like to check it out :) http://www.youtube.com/watch?v=Tvnhwc_j5Mo
