The use of theme was interesting. I liked how you can't see the spirits on the map but can't see the path when you're not using the map. It adds some difficulty. But it was still easy enough that it wasn't much fun. If the number or speed of the enemies changed as you collected keys the gameplay could have been more interesting. Its cool that you allow the player to choose how many hit points they have and keys they need to collect in the options. The art was nice, but the size of the screen was very small (I zoomed the page in though). And the music got repetitive.
