Nice how much you managed to do solo in those two weeks! The music, the graphics and of course the programming. It reminds me of a retro Genesis game like Shadow Dancer, both visually and musically.
I do think the levels were a bit repetitive. The level layouts were new, but the bosses were the same (just a different weapon) and the enemies didn't change much either.
Overall I'm still impressed with what you managed to pull off in such a short time!
PS: I love how you can pick your character at the start, especially the furry ones!
