I believe this was your first game? Absolutely stunning effort! Only complaints, basically what Tim said on the stream about the blood cells looking like something to avoid (although I knew to avoid them because of the stream) and the feedback when you hit the wrong one doesn't feel like much of a penalty, maybe some kind of screenshake or moving the camera in such a way it feels like you've slowed down a lot would be better. Only issue I came across is sometimes the sound didn't fire when I swapped between cells, but that's a minor issue. Loved the atmosphere and the music and the game was really fun. Well done!
