Thank you for the kind comment! I'm glad you liked the atmosphere of the game.
I was a bit afraid of making the puzzles too hard, so I'm glad you found them easy. I think I'm fine with them not being difficult, as it's such a short game anyway and I don't want players getting stuck.
I see what you mean about solving some puzzles by accident though, that's definitely a design flaw. And you're right about showing the solved puzzle to the player instead of fading it away directly. That would be easy to fix in a post jam version and I think it would feel better when playing. Thanks for pointing it out!
