Alright, made it all the way through. Conceptually and artistically, the game is fantastic, but the execution is where it falters. The slowness of the character makes death more tedious than frightening. Having to go get the sewer key multiple times was a slog. And it doesn't really make sense that you can only use a bed once. I'd suggest switching that mechanic for diary pages. It'd tie our story more closely to Cathrin, and it's a more finite resource than a bed.
Edit: I do disagree with Eshball on the puzzles, though, they were fine. Heck, I thought the moth guarding the switching station was super clever.
Edit 2: Also forgot to mention that none of the vertical cart models contain coal. Figured out I could burn the second batch of moths by accident.
