I... I'm not entirely sure if this is a glitch, or an unintended, once-in-a-blue-moon idiosyncrasy: http://i.imgur.com/aZvJhsv.png
Pretty obvious what happened; I entered the level, jumped on the jump pad, and got caught between the horizontal ones. This lasted a couple seconds, after which I "wiggled" my way out of there and carried on with the level.
