This was almost a perfect game, but I was very close to giving up before figuring out how to clear room one. I kept putting my tool in the slot without knowing i needed to click the screen first, and was just guessing codes and trying to remember the access code. I probably restarted the game 5ish times since I thought I'd done something out of order and broken the game, and I don't usually give jam games 5 tries but your atmosphere was soooo good I really wanted to get it to work.
Some sort of indicator to show what you can click would have been great to remove most of the frustration, just some faint light up when close to an object you can interact with or something similar. At this state since you can't modify the game, you should at the very least add some instructions on your game page on how to clear room one, since after knowing how to clear room one the game plays fantastic.
The graphics are absolutely perfect, the way you handle lighting does a fantastic job setting the mood, audio is fantastic, and gameplay is really fun and creepy and you handle pacing really well, the second I wonder if all the game does is press buttons in rooms you start implementing new creepiness.
Almost 5/5 across the board, but I also almost gave up on it without even getting to play it.
