Could use more
It's good, and a cursory search on the internet came up with a version with antibodies I think. If that version is available, it would be much more interesting. At around lvl 30 I started getting bored... it was difficult until I figured out that increasing your buddy is all you need to do. I would take the buddy out completely. At lvl 51 I figured that with a buddy maxed in size and over 100 speed with about 1000 life will mean I can just sit there and not play the game, let it play itself. And the high score doesn't seem to be working. I wonder if my score of 2.7 billion is a record or not...
