The visuals of this were very creative. Hopping from page to page was incredibly interesting to look at.
I noticed that you're still affected by gravity during coyote time, and in some cases, this makes it almost like a double jump, where I could fall off a platform and then jump in midair when I land. Though it's not noticeable in practice, I only found it out because I intentionally tried to test the coyote time.
Despite it not taking long to finish the game, it felt like it was a lot more content-dense than it was! It was always engaging in some way
lastly, the collision boxes for spikes, platforms, and the player felt a little bit too misshapen for tight squeezes to feel comfortable; It felt like the player was too big in comparison to the others which made it feel unsatisfying trying to land on the smallest sized platforms
This feels like a very inspired game overall. The writing was good and it was satisfying to finish. You got a lot done in a short time, great job!
