demo feedback: I don't like that the climax part repeats three times (partly I just find it too long, partly because I don't like your ahegao faces, sorry) so I'd like to be able to press E to skip during a scene, not just before. And also to skip the cg images, sometimes I find they display too long. Just give me control over when I move on, by pressing E. I like when sexy stuff feels like part of gameplay, not a pause, so I make it fast.
Otherwise game seems nice, given the constraints of being a solo amateur passion project, I assume. Not enough futa-only games with actual gameplay and I like your character art is more on the thin side and how cartoonish it is. A little too easy for me.
