I like the idea a lot but I do think there could be better execution.
I think at the start the game needs to guide you along a bit more. The levels with only white cells I beat without thinking, but as soon as I reached the level with the red squares I was stumped. I did figure out that the red cells would kill all nearby white cells, but I couldn't figure out WHY I would want to do that, when my goal is to keep the white alive. if there was a level that showed me why I need to use a red and how I can use it, then I would enjoy it more.
Again, I really like the idea, but it did need better execution.
