Good:
Graphics are really well done!
Atmosphere is great!
Level design is good. Never did find the yellow key though.
Pixel art is amazing!
The typing out of messages was a nice touch.
We liked that you could close the doors again.
Enemy design was cool!
It was really scary!
Could be improved:
Camera was a bit jumpy, should have lerped between rooms.
Beeping got jarring quickly.
Flashlight cone should have been smoother and wider.
Sometimes the enemies would flicker out, probably clipping under floor or behind camera.
