This was pretty enjoyable. I liked the use of lighting; it really made me feel like I was exploring a dark ancient crypt.
The critiques I have are kind of scattered. For starters, there should be more contrast in the colors of the floor tiles versus walls and obstacles, that way it can be easier to see where you can and can't walk. Second, I think the enemy pathfinding could've used more work—I had at least one enemy get stuck behind a torch. I also didn't see any enemies pass between rooms to search for me, which would've made the combat and trap-setting part of the game more interesting, in my opinion. Finally, I got a recurring bug where the camera wouldn't follow me into another room if I traveled between the two rooms too quickly.
