This was really fun to play through. I missed picking up the traps on my first run which made the final boss arena maybe a bit more challenging than it should have been. Given that I don't believe there is any way to backtrack, I'd be curious if you could block the player's progression somehow or otherwise foreshadow that I was about to miss something really important? The other thing I'd be curious to see here would be a little bit more light in places or some other in-game mechanism to compensate (a flashlight, lantern, etc). The visuals look great, but I found myself getting lost in the dark way too often because the light dropped completely to black. I suspect that even just the smallest bit of global illumination could go a long way here without compromising on the horror vibes the game gives. Nice work!
