Thanks!
I can't quite remember which level was level 5, but it is a bit hard to pass the monsters through those bridges, I couldn't think of another way of making those while still making it seem like without the bridges they'd fall (I couldn't just make the gap wider and leave a blank space, they'd "fall to the void"). It's hard, you just have to scare them and try to get them to go 1 by 1.
