So I've been wanting to get back into speedrunning for a while now, and I've been struggling to find a game that would suffice as my return.
I also just so happened to have played Antichamber, a mind-bending puzzle game, pretty recently.
This is my best run so far. Sure, there are some flaws, but I'm happy I got the really difficult tricks, like early Link to a Chain Reaction and the cube transfer en route to the red gun, first try with pretty good speed.
Note: at the very end, I got stuck on the edge of some level geometry, and I barely made it. This was completely unintentional, but I'm happy that I still managed to get into position to finish the run on time.
