Rory will leave a mark on walls he runs into. This lets you know what direction you came from or have already been to. The damage starts as a small crack, that turns into a larger bear head-sized crater after the same location has been hit multiple times. Laser beams will leave a large, black scorch mark that remains the same for the entire level. Because lasers cycle on and off every move, use those marks to know where the laser will hit the next time it turns on.
