Nice idea on the game. I enjoyed it. I did however have 2 issues. The first one was that I changed dimensions in a room in the upper left and ended up on top the world level and fell out of the world endlessly. Then I felt like the overall speed of the ghost was too fast. I kept missing platforms by overshooting and what felt like a slide. I think just decrease the speed a bit and tightening up the jump a bit would make the character feel so much more responsive and fun. This is my opinion. The overall game play was fun and did really enjoy the dimension shift to get to other areas of the map.
