This game has such cute art, even the enemies! I feel like I finished the game without ever needing to worry about the shrinking light mechanic, or even notice it really, so you could definitely up the challenge quite a bit. I also found some frustration with the controls, since the angle you walk at when going diagonal isn't the same angle as the hallways, so you constantly have to change which direction you're walking to go in a straight line. Other than that, this was a fun little experience!
