This is a video of me, Tasselfoot, beating Whiteboard Tower Defense on Hard mode without juggling. AFAIK, nobody else is using this map set up. It works fairly well, as long as you can get past the 1st boss (level 4). If you don't kill the 1st boss, restart. If you do kill the 1st boss, you'll win... likely without losing another life.

Video is on 8x speed, because it was around 48 minutes normal time.
