Pretty nice game you made in such a small amount of time! I like how you interpreted the idea of diseases into the boss fight. The performance of the web version of the game is really poor; however, I downloaded the Windows version, and it worked like a charm! Seeing a cutscene after defeating a boss was really cool, rather than just some text saying "you win". The player's bullet speed is really slow, but the boss bullets were so fast that I felt like Neo from The Matrix when dodging them XD
