1D Soko version 2

1D Sokoban (version 2)
More levels, more "difficut" :D ... and larger than 2K :<

Use SHIFT-key to open and close the hidden spaces in the level,
left and right keys to move your avatar, the > character,
R to reset the game, if you get stuck or want to play again.

The goal is to move all the boxes on the platforms (like in the original 2D Sokoban).

For the audio I use the ZzFX.micro library by KilledByAPixel (github ZzFX).
