Super original mechanic! It's really refreshing to see a top-down platformer game, and the way you interpreted the theme was really cool! I loved how you made the "checkpoints" a quick flash into reality, and the jump sound made it really satisfying to parkour around.
I do want to say, some of the platforming challenges were a bit finicky, and I felt like I lost for no reason even when I shouldn't have because the jump was hard to judge. I do understand that this problem is pretty inherent to the unique approach of a top-down platformer but I still wanted to point it out.
I also think you could have shortened the levels a bit, I do feel they dragged out a bit too much.
Overall this is a super charming and fun entry and integration of the theme, great work, and keep it up!
