That's so cool!
At first I thought - "hey that's a cool take on a platformer, to have a gravity swap mechanic to solve the levels" and then the dimension swapping mechanic kicked in - I love it!
I gotta admit, at the first level with a box and a button I thought that something bugged, because the box wasn't activating the button, but after a while I realised that the button might be not aligned with the box in the 3d space so that's on me hah
Super fun, great job!
