This game is a smart mix of mechanics and design principles. I enjoy the sexual mini-game and the resource gathering, and the pose system and art style seems to be a good way to simplify further character and scene implementation. Let me also thank you for going out of your way to make an actual game, rather than another VN.
If I had to give a criticism, it's that the game is obviously low on content at the moment; however, it's clear that you're intending to shore that up quickly. At the point that you start fucking Cami at mach-5, though, I think she should probably stop saying "You're doing great! Keep it up!" ...maybe one last phase for the girls during sex would be a good idea?
I'm guessing that there are 9 girls planned, since there are 9 resources/biomes? I'd also guess that there are at least 4 more poses planned, although very likely more. In addition, I can only guess at how the heat mechanic will work. I wish you the best of luck in completing all of that, and I hope that the development goes smoothly.
