  • I don't think this works if you overload PLMs with a power bomb.
  • canInsaneJump doesn't seem necessary.

This is only used as a difficulty placement, but maybe something else should be used instead?

I don't think its that unintuitive relative to going up through the crumble block even if I haven't thought of this strat before now.
