Thanks for the feedback.
The tileset is created by pixel poem - no credits for me ;)
I also had a few ideas to make it creepier adding camera shake or blur if you see an enemy. Actually I added footstep sounds to the game but in the end I forgot to use them. There are a few features I ain't managed to implement due to lack of time (and dwindling motivation). As example, all coins have no use :|
It was a nice little jam and creating horror games is a lot of fun. I want to go for a 3D game next time :)
