This game was one I was excited about from reading through the devlogs, and I'm glad it turned out so good! The art and presentation is beautiful, especially considering you're using an engine meant for Lucasarts-style games. I enjoyed poking around the room a lot, it's a very rich environment for three screens. (I like the lighthouse photo joke.) I like that combination lock puzzle - putting the clues in the room together was satisfying. I didn't spot any bugs or glitches.
The one big thing that bothered me was that the inventory items should have descriptions - the letters repeat their contents, which is great and exactly what I wanted, but I think the photos should do that too (especially since one of them has a puzzle clue!) - right now the photos and the hat are just "some junk in my inventory," which conflicts with their importance in the story. Maybe that's just because of game jam time pressure, though? Anyway, your game is great :)
