Holy crap, this is an amazing game! Very nice concept, the last level took a couple of tries but it was very rewarding to figure it out (I’m not going to spoil it for the others)!
One tiny bug I’ve found in the last level: if I try to spawn a copy while standing under that platform, the copy spawns on the platform and gets stuck. Maybe you could check for overlaps when spawning the copy and disable collisions temporarily and only turn it on once the freshly spawned copy is no longer overlapping any solids.
This is my favorite jam entry so far!
