Music and graphics were great and went well together.
The platforming mechanics were however very frustrating. Very steep learning curve on the gliding which I think most people would not be able to pick up very well. If I'm even understanding how it works, it behaves like a jump which can only be triggered in midair. Works well for falling and steering, but jumping gaps was very difficult and I found myself spamming Space and Up keys because that seemed the best way to ensure that the glide up would trigger.
After I picked up the ghost (which looked very cool btw) and went through the 2nd door, I appeared in the 3rd scene with no ghost, and a seemingly empty scene. I couldn't figure out how to progress from there, as all I could do was fall into emptiness.
