This is great so far. Dark, mysterious, almost spooky atmosphere with an interesting story we are getting just enough of a taste of to understand the broad strokes without giving everything away.
The art is also great and I do like the stat system. It encourages doing multiple playthrough to see more of the story or sex scenes. The game is short enough that doing these multiple playthroughs isn't a chore. Would be nice to be able to skip the intro on a second playthrough though. You can make a save immediately after the intro so it's not a big deal and the intro isn't particularly long but still.
Great job! I'll be keeping an eye on this as you update!
