Clever! I like how the jump is up on a high platform, it fits a theme.
Gripes: I've had a heck of a time trying to use the grapple, it seems like I can never estimate correctly how far down I'll end up at the end of the swing, as if it gets longer. The orange area has too few checkpoints for me to put up with the frustration for now, I'd like one after making it to the end of the first left-to-right section. (But it may just be too hard for my slow reflexes.)
