Really liked the idea for this game. It did take me a minute to realize there is a book at the bottom right explaining how to fight each virus and the mutations, but it's not that much of a problem. I did notice the music stops at one point and never returns, not sure if just me. Overall, nice game, great art style, I'm interested if there'll be a full game like this, having to defend different Bloodstreams or with new mutations for viruses to defend against
