Very very nice aesthetics in this game! It is very polished too, and the story is intruiging. I didn't make it further than room 108... dunno if there was some way to get further.
If I should point out something that I would've changed, it would have been the piano music, as it made the atmosphere almost cosy for me personally. Like, I was pretty chill playing the game. If you wanna keep that music, I would probably put it somewhere physically in the game (like someone is playing the piano).
Otherwise, extremely positively surprised!
