This game is honestly lots of fun, and each patch has consistently improved the overall gameplay and experience by adjusting what needed to be fixed quickly and correctly. The enemies have great variation, and each has animations that fit their overall theme just right, which makes for fighiting through the enemies to find new ones a really enjoyable experience. I personally enjoy the cave and space station enemies the most because I'm honestly into it, but I feel there should be a warning for bloody effects in the animations which weren't given when I first started to play this. Maybe there's been a patch since I've posted this that fixed the issue I find with it.
I believe the dev has said that there'll be more levels and roughly 4-ish enemies per level to fight and see what they do, and I look forward to it. I wish there was more mind-control and hypnosis themed stuff in the game, but I hope there'll be more of it avaliable in the future
