This is a lot of fun!
Some great touches here, like that we can't run off the edge, only jump.
Artstyle and animation is awesome. Music is simple but super cute.
At first I didn't understand that the hoops were doors, I thought it was a bar for a lock or something. But once I figured it out it was smooth sailing.
Satisfying little puzzles to solve, and nice mechanics eg the unsteady blocks. Swapping between players feels really nice.
Great work!
