For a game Jam project, this was perfection! Finest job. Yet, the mechanics were unnecessarily difficult.
There are 2 main perspectives, based on how I give the game a positive feedback - immersion and the struggle I had to encounter while navigating using the keyboard+mouse. First, I think the level of detail with these specific mechanics are superb. I literally felt as if I was crawling and that adds true depth to the horror, which I have not seen other games do. With that said, after couple of minutes I was irritated and overwhelmed, which is the reason why I quite the game.
I fully understand that this is a game Jam project. If you were to develop or update the game, I would recommend trying to find the balance between the 2 sides, which I mentioned in the paragraph, because the game has a great potential and it is super engaging.
Best of luck with the future developments and with the Jam. Cheers!
