A magnificent game. I've added it to my Steam wishlist.
I want to mention two things:
1) It's really lacking animations for climbing onto objects, such as crates, etc. - the regular jump looks arcade-like, and I'd like to see more realism. As an example, there's a game called The Killing Antidote, and the animations there are top-notch. I recommend checking it out for inspiration.
2) I would really like to see a separate development of the Evolution storyline. To be honest, this storyline was more interesting to play than the main one, but it's a shame there's so little of it. I don't know if you have plans to develop it further, but it would be cool to see some missions like: "defend the nest from attacks by survivors" or "capture new girls for incubation," etc. In some ways, this storyline might resemble Kerrigan from Starcraft.
I wish you good luck with the development!
