This is really good, it reminds me of the Friday The 13th game (RIP)
In terms of feedback it's mostly minor stuff.
I'd have interact on E and flashlight on F.
The marker above the monster's head showing if they were investigating or alerted clashed with the atmosphere, maybe a visible in their movements, and audio queues so the player isn't 100% sure, to keep the tension up.
I think sprint having a stamina would make chases scarier.
I'm on the fence about the inclusion of noise generated, I didn't even think to include it in my game and when I saw it I was kicking myself thinking I should have, but actually I'm not sure, it's communicated the gameplay well to the player but it also parameterises the tension of sneaking vs speed. I may try it out for future versions of my own game, thanks for the idea haha.
