It's such a classic, I love everything about. On top of it being a decent puzzle on its own, it's a steamy hot NSFW game (the dialogues throughout it really help build the mood), the characters are well-written and there's an actual plot that breaks the 4th wall, and the ending almost made me cry a little C;
I would imagine this must've took a long time, but I gotta say you have a great artistic mind, and I hope you make something as beautiful in the future.
