Really nice art! And the puzzles were pretty fun too. The dialog system (with sound effects) was really well made, although I wish it wouldn't repeat every time I reset (or at least be easily skipped?). I have no idea what this universe is, but the overall style and story was interesting to follow. The main bedroom had a spooky vibe to it, very atmospheric.
I did indeed have to use your spoiler to beat the last level though.
