I really enjoyed playing this game! I loved the humor in the creature's thought process (or lack there of), as I could certainly imagine wanting to be left alone on a remote planet. I really appreciated how each mutation felt appropriately paced such that the drawing was well-integrated with the on-screen clicking, and I was never fully pulled away from either task.
I wasn't expecting the end to involve losing/winning (or at least that it wouldn't depend on the free-response fields). I evolved a big curved beak, cephalopod eyes, many centipede arms/legs, and the ability to spray poison gas in order to defeat the warplanes. When I failed, I was prompted to redo my last mutation (I chose a human face for communication) but failed again, after which the experience abruptly ended. It felt a little sudden and disappointing, as I was hoping to hear my final thoughts and/or experience what dying felt like, and maybe receive stats at the end (like some other players apparently did).
I was super intrigued by the description of "coming back one more time" and the implication that I had memories and notable experiences before the start of the game. It continued this game's pattern of dropping small bits of personality/characterization throughout the experience, which was fun to experience.
