In general I like the idea pretty much. And it could have been a lot of fun if there not were two points which totally frustrated me:
1. The Ghosts / Djinns are way to intelligent. They follow me right up and I have no chance to escape.
2. I could not walk "behind" a tree. In my opinion you should definetively consider to disable the collider of the upper part of a tree.
But I really like the concept and the art and music are really great.
