Version 3 changelog :

- Added a new level "Blind Loopover" where the letters disappear when you start moving the puzzle, make sure to memorize before solving. 4x4 mode is also included.

- Added sound effects for moving and completing the puzzle.

- Added different starting points to the music when resetting the level.

- The music no longer gets pitched down when playing in 4x4 mode.

Version 2 changelog :

- Modified the controls for future compatibility with OH. The delay before each move is now gone.
`Focus` -> cycle move direction
`L/R` -> change line number
`Swap` -> execute move

- Added a proper scoring system for competitive play (18,000/time). The less time you take solving the puzzle, the higher your score will be.

- Added 4x4 mode for an easier challenge. Lower the difficulty to 0.75 to access it.

- Like the score, 'Solves' and 'Best Time' are now updated when the puzzle is solved instead of when it resets.

- The puzzle no longer has a chance to be "scrambled" into the solved state.
