Sokoban: Old School Edition
Sokoban is a transport puzzle in which the player pushes boxes around a maze, and tries to put them in designated locations. Only one box may be pushed at a time, and boxes cannot be pulled.
Sokoban: Old School Edition strips game down to the essence. No crisp colors, fancy sound effects or millions of polygons. There is just you and 50 levels of intellectual challenge. Oh, and the glowing orange ASCII console back from the 80s.
