My mind hurts just to think about the challenges this mechanic can provide.

Very interesting and clever game. Nice job!
I have yet to play Recursed but Antichamber is great.

Finished the game! Took a while though to figure out the main mechanics but it was cool :D

This is cool! I had to look at a walkthrough to learn the portal drag/drop mechanic, but after that it has some neat puzzles and a cute side story.
