Very nice game! As soon as I got to the room with the drawings in it, I at once though 'oh! this park is actually in someone's mind!' I think the little drawings really tied that up. :) Also, chasing ghosts and other ghostly creatures was rather fun!
Controls on a keyboard were a bit rough and the character was slow moving/turning, and I ran into a couple of invisible walls which I'm fairly sure weren't supposed to be there since I could walk around them and they were within the safe part of the park. But it didn't really bother me. :)
It amused me that the trees turned to accommodate you as you walk past. That was a nice touch. Made it feel dreamlike.
