I like the idea, it's simple yet effective. The duration of ghost spawning is well balanced, as well as movement and jumping speed, and level sizes and layouts. However high acceleration with non-existent deceleration creates uncontrollable movement for no good reason. I'm usually dedicated enogh to complete any jam game, but this time I couldn't finish 3rd level, and ghosts have nothing to do with it: it's just difficult platforming alone. In a jam game that's supposed to be about loops and ghosts, it distracts from the core idea too much.
At the same time, I find both visuals and sound super good and polished. Starting cutscene with big hand reminded me of World of Goo's absurd style in a good way. Great game, good job!
