I haven't been playing for very long, and am already stuck. This seems like a bad sign.
I can jump to the sides and touch the nodes, but instantly fall through the floor and lose my progress. Without the charge I don't have enough height on my jump to get through the ceiling.
What am I missing? Is there some logical way to do this? Or does it just require more dexterity for the "Jump and back again" than I possess?
