Interesting game...reminds me of Heathstone but the mutative element is fascinating. I was having some issues understanding which body parts would yield which benefits to the mutated creature, although I suppose that was part of the challenge. I understood each base creature's benefits and special abilities, but deciding if I should use the ant legs versus the thorax when combined with the goat's head, etc., that was difficult to optimize. By the time I got to the flyer boss, I was fairly flummoxed! The challenge seems to mount exponentially based on the new enemy strategies which precede your own access. Really nice game.
