Such an interesting game, I loved the strategy that you can put in this by multiplying and differentiating your units.
At the beginning I thought that the merging action would give me an additional Roshambo element, but then I discovered that it replaces the original one. That makes more sense, because it requires you to multiply first (by gaining the blood cells) and differentiate next; this is some cool game design, and a good way to direct the player's game. Good job, congrats!
