Beta Build for Class

Beta Build settings for class on 11-13, still needs refinement. TODO:
- Flow between puzzles. Victory screen for a moment and then send the
player straight to the next puzzle
- Remove 3 + 4 links from puzzle menu (empty puzzles w/ no start + end)
- Remove Options + Exit from main menu for now maybe? They're
non-responsive buttons ATM
- The Sound buttons on puzzle 1 + 2 are out of place and upside-down,
please move them back in place (should be quick)
