Has a fast and smooth flow that feels really good when you get the hang of it. One gripe is it was sometimes difficult to judge if the height of my jump would be enough to reach the next platform.
It'd be cool if some of the levels had a bit more depth, perhaps in an expanded version. As in your ghosts need to do a little more, or you have to plan your path and order of events. Because currently each level is the same in structure where you take one path the first time and then a second path the second time.
For instance, maybe ghosts have to open paths for each other several times? So on your final run, you have to be in all the right places at the right times instead of just making a beeline to the goal. The concept reminds me of the Clank puzzles in Ratchet and Clank: Crack in Time, where you record copies of yourself.
Had fun though! The music was cool, and I liked the stylized art of the ghost!
