Cool project and concept. Could be something big in the future if you continue working on it.
Same as others before i encountered bugs and crashes. When I looked at the note before Room 3 i always got the error down below. Mashing E can actually give you multiple items at once, so if you mash it when looking at the heal kit you get multiple. And crouching sinks you into the floor and you sometimes dont get up really good, you have to do some weird crouch movement to get unstuck.
Some additional feedback, the puzzles are really hard and i think need a little bit more explaination, like hitting the lock opens the door when before we used actual keys. And the items you can interact with look exactly the same as items you can't interact with, was looking for the note 20 minutes. The keypads are really difficult to use, a better idea would be a zoom in and you are using the mouse then, or atleast show the number you are hovering over atm. The gun seems massively underpowered, what i would do is, make it a onehit kill, but you only find single bullets, this means if you screw up you have to go melee. Melee seems a little bit overpowered, you just go in hit and go back out and you dont get a hit. Its not really clear where the health screen is and using a heal item has too little of a response, using multiple here is something that will happen quite often.
Hope you continue working on it since it is a really cool project. And I hope you don't take my feedback personal or something, I give you so much feedback since this could actually be a banger of a game and you need to know what works good and what works not so good.
