I might redo this one in JSE.. Though, it is alarmingly more complicated than I expected, code wise!
Could JSE keep up with it all!?
Hmm...

Clamped can run around the edge of areas, and "flip" to the inside/outside.
He can also now jump, leaping to the opposite side of the area.
I've added goals in each level, as well as pickups.

Today I need to add some more dangers.
Petit Clamped has black rectangles that float side to side, so I think I'll probably be reusing those.
Add a time limit, and .. We should be good to go, I think.

A little balancing, and extra playtesting should make for a well rounded platforming game.

Gud gud!!
