credit for tweaking up the genre
I liked the fact that the fat and antibody units were added to put a new twist on the game. But in practice it still turned out that the best strategy seemed to be to capture as many of the unit producing cells as possible as quickly as possible, and only worry about the fat or antibody at the very end to take over otherwise unattackable cells.
The other tweaks to the game - offering difficulty levels where you don't get to see numerical values for strength and having fog of war obscure enemy movement - were also a welcome addition. But again, they didn't end up changing the game play mechanics, and didn't affect what seemed like the optimal strategy of capturing unit producing cells as quickly as possible.
