Nice short game with great art and an intriguing idea.
More or less all (small) things I would criticize have been mentioned by other comments (I am happy I wasn’t the only one soft locking himself).
But one thing I personally don’t like are the music and SFX. The music is too repetitive for me (good in the beginning, but if you play longer times - because you have to restart for example - too much for me), and the SFX can be quite harsh, especially the Hideous Hymn has something at the end of the sound which is just loudly “scratching” in my headphones. The same thing is not as bad with stereo speakers. So for my run through I just muted the tab.
But it seems others like the music and SFX, so my opinion might be an exception.
