Incredibly fun game. Swap mechanics are SO GOOD and it's really smooth too! On the first keys level I tried so so hard to carry the key over the top of first door to open the second one UNTIL I ACCIDENTALLY REALIZED YOU CAN KILL THE CULTIST TO GET NEW KEY :facepalm:
Boulder throwing spices it up even more, though there seems to be an unintended bug, where I could jump after swapping with a mid-air object, if I was previously on the ground. It leads to some two-boulder-swap shortcuts of whole levels sometimes (I could do it in only one level actually).
It's not initially clear how to beat the boss, but he's easy once you do. Cutscenes are hella slow though ughhh..
As a huge fan of platformer games I really really enjoyed this one. Good job!!
