I really like your game! Kudos for you doing this all by yourself. I liked how every disease had different stats and behaviour. I actually fell off the platform in my first try because I didn't realize the shooting pushed me back a little, but once I got used to it, it kind of added to the gameplay and I used it to manoeuvrer around. The camera didn't really work well for me though, sometimes diseases were hard to spot because they were behind the heart, and I felt that the diseases that came from beneath were too close already when they appeared on the screen. Overall a very nice, funny and well polished game. Great work!
