Realized too late on that you could rotate while holding a mirror (that info is on the game page) but. Had a quirk where I was able to go past the closed door by jumping on the fallen pillar but it didn't advance to the next level, I guess I had to walk through the doorway using the normal mean of solving the puzzle.
The atmosphere, music and low poly style is spot on, the aesthetics are great and gameplay is short and sweet with puzzles smoothly scaling in challenge. Great entry!
