The character looks weird, I think you should use two-sided materials for his hair at least. The overall atmosphere is nice, suits the grave theme pretty good. The levels seem a bit big so engines are hard to find. I would add a sound to them so you can tell when you're getting closer and not spend so much time looking for them. But in the end, the game style isn't that suited for the theme. Repairing engines in a graveyard while some RPG monster is hunting you down is weird.
When I saw the picture to the game I thought I was going to be an orc bashing down doors... Disappointed to see I'm only human.
