Loved the artstyle! The little clapping effect during level transitions was a very nice touch :)
Some of the levels could have benefitted from slightly better timing, it wasn't the most fun waiting around for the platform-clams to get into place just right after a respawn
The high double jump was sometimes hard for me to trigger
I did however make it through a bunch of levels and had lots of fun doing it, so it clearly wasn't that much of an issue!
