This was a solid entry. Your pixel animations hold up to the standard (of quality, if not quite the same proliferation) as Life of the Party and that's a very good thing, probably the biggest of small touches that makes this one fun.
There's a spot or two where it's not entirely conveyed whether a jump can be made, at least without taking damage, and in at least one instance (I think it's over a pool of lava with a pretty low ceiling) it seems you pretty much need the grace-time. Most of my nitpicks here are just that, though: Nitpicks. Good job overall!
