Couldn't have made this harder even if I tried. Got stuck in level 4 and now level 9, I don't have enough space to maneuver the stupid enemy spawns and I don't have enough time to spawn all the platforms on half of the screen. I think what's more annoying is the enemy spam especially the damn ghosts that follow you around.
Jeez, I don't even want to think how much worse it's going to get by world 3.
