I really liked the intro! I admittedly got stuck way to long on the second level, but the puzzle itself isn't actually that hard, I was just being dumb lol. Unfortunately i got stuck physically on the 3rd level, don't know what happened, just walked into a wall and suddenly my character wouldn't move anymore.
I don't think it's a bug worth fixing however, I was holding shift and pressing left and right really fast and got wedged in probably the only part of the map I could have haha.
