The game is amazing. Incredibly simple. With a optional cheat code that makes the playable portion look pratically like a living gallery, with no obstacle at all. Very good pixel art, but above all, the two things that made this game great were: the setting and the characters.
The setting is just the right mix of comfy and erotic, although the lack of certain restrictions(such as not being able to walk naked at all places and screw anyone everywhere) prevent more dirty and creative playstyles.
The characters are what make this game special and sort of immersive. It's fantastic how much personality the creator was able to give to these characters, through unique positions, clothes, actions, responses and also the backstory. While there's nothing explicitly said, there's just enough implicit here, to give the player a good imagination of what each of the character's preferences are, who they would be better match with, and fabricate a story around it.
Given enough imagination, there's certainly things that would make the game better, but that doesn't invalidate how very good it is already.
