I don't know your design intention, so I can only subjectively say my feelings and thoughts:
The atmosphere is good, the art style is also very unique, but the combat part seems a bit simple, I saw that in your past videos, similar to the resource management in Resident Evil (bullet and dagger), why are they missing?
It may be that limited resources make the player more nervous, and it may even be possible to simulate that tension by holding down a button all the time to hold the gun.
Creating collectible resources also encourages the player to explore the scene.
I think the The puzzle part was OK.the puzzles are concise, and they help rather than hinder the player's participation in the environmental narrative, and I'm interested in the story, so I'm looking forward to your updates.
