Hi, thanks again for the feedback.
I just finished an update that adds a sanity system and hallucinations to try to get that feeling of unease you were talking about. I also added some small things like footstep sounds and ambience to make it feel more immersive. I will try to work on this more in future updates but its a start
You can read the devlog here if you want.
Your advice was really useful and I just wanted to let you know that I appreciate it.
