If you're talking about unclear instructions, I assume you mean the book "puzzle." As I mentioned in a comment, the game—especially the box hitboxes—was very buggy, which often led to unfair losses.
Regarding the book puzzle, it’s what I called the third type—the trickier one—where you need to match the book’s spine, not the cover. I assumed players would figure it out after a few attempts. I had a hint in mind, but unfortunately, it never made it into the game.
As for the atmosphere, I’m really happy that it came through. As the developer, it’s hard to look at your own work objectively, and without playtesting, it’s nearly impossible—which, by the way, this game wasn’t playtested. Anyway, appreciate it man and thanks for playing!
