I really enjoyed it. It reminded me of the scary maze game a little. I like that it is dark and the gameplay has a lot of potential. I got stuck at layer 4, I'm not sure if I bugged it or if it isn't possible but there was no way of getting to the end without restarting the level. the items that get dropped after death couldn't be picked up most of the time and when I did finally get to pick up it didn't do anything. Overall I really like the idea and I think you should be happy with what you made.
Please check out my game if you get the chance, There is a gameplay video if you don't have time to play but I would be happier if you did :)
