Impressive so far. I saw that some sort of story mode is planned ? Always a bit scary as they seem to distract the devs from adding actual meaningful content to the game for a story mode than often doesn't even end up being released, or released in a very poor state. I'd rather see the sandbox being fleshed out before starting to work on a story mode. That way there would also be more assets to choose from and make a better story mode from the get go.
But will see.
If I can give an actual suggestion though, it would be to allow semi-clothing, e.g having at least 3 states for each piece of clothing like they do in Illusion games. Fully clothed, semi-clothed then naked.
At the very least for panties, I find it nice having panties on when doing the deed, but preferably without having to clip through it.
Good luck with this project though, could very well become a classic.
