Great game! Loved the atmosphere and this is what I wanted my games gameplay to be like. I would definitely buy this if you put this on steam.
Edit: Just watched the walkthrough and I beat the game while only solving one puzzle. I somehow clicked the objects in order and randomly clicked the wall. Despite that I still loved the game and just assumed the puzzles weren't finished. My case is very unlikely but probably make sure there's a check like an if statement to make sure they unlocked the closet. The puzzles are great from what I saw in the in the walkthrough.
