There's some cool levels in here and the game play has brought me back a few times from typing in this text box.
At least at the moment I'm stuck on the "escort" level - staying within the safety zone that moves around the square. It gives me conniptions.
Having the room state persist between deaths is kind of interesting and can help you see stage hazards that are obscure at first glance but... kind of gets in the way when the only way to move through the stage is gated by a 10-15 second cycle.
tl;dr: neat game, overstepping out of the patrol square in whatever stage that is and then dying makes me froth.
