4D Sokoban

Sokoban, but in 4 dimensions. Left board moves in XY, right board moves in ZW. At first, the game might seem extremely unplayable however, if you persevere, youll end up developing enough intuitions about 4D space to make the game just about barely unplayable. Original game by Beekie, with a level from Corey Hardt. Modification by knexator, inspired by Tilmanns variation
