Prevented jumping off the hexahedron in Snapshot

Completely reworked the level to teach mechanics required for later puzzles

Added new level

Comment:
Recorders are much more cursed than I thought, so some designs may be based around "interesting" behavior. I'll only include it, if it is consistent and can be logically taught to the player. Perhaps Croteam will fix some of this before release?

Way Too Many Barriers
- Made barriers higher to prevent jumping multiple
- Minor cheese preventions
