I was able to finish the experience. The tower bit was pretty cool! I loved the music and forest scenery, and for a 3D game I felt it was the perfect size environment. Serene is the proper word to describe how I felt playing this.
Some of the physics were rough around the edges, and I only found one spirit despite seeing more than one. I also felt the story could be developed with the intention of finding more than the "item in need" at the end of each level. Perhaps I have more to learn from this game, but time is running out. Well done!
