This was fun!
I enjoyed the implementation of looping and being stuck with no real way out. Even after escaping into the light you still loop back when you press play again anyway.
I think the UI was the weakest point here as in my opinion it was a little too big on the screen which meant I couldn't see much of the tile I was on leading to me getting a bit lost at times and you can't see health/sanity in the inventory.
Sound design was very good for instilling fear as you can hear the enemies stomping around you. I didn't use stealth much as it was a little hard to pull off with the movement system and a lot of enemies would just be blocking the path anyway.
Balancing health/sanity with the items was an interesting mechanic and I like that you had to use consumables to get stronger rather than traditionally gaining permanent power.
