What a fun concept and great to incorporate secrets and time challenges into the game. I liked the little story and especially the overlapping worlds. It's implemented simply, but very well.
Your art was AI generated and that was visible. Not that I mind that it's AI because of the time constraints and not everyone is an artist, but that you really saw the imperfections in some of the eyes.
My other feedback is about the controls. They feel weird and the acceleration feels uneven. On the other hand, it added another dimension to learning the controls. There is a jump in the first ghost where I got stuck, but when I got the triple jump there, it felt great. Good job, keep it up.
