All instructions in-game, but just in case you forgot: WASD for character 1 movement, with SPACE BAR being the attack button ARROW KEYS for character 2 movement, with P being the attack button DIFFERENCE FROM CLASH OF COUNTRIES 1.0.2 The difference is that more variations are made to the maps, and more shapes are added. Further updates will include more shapes.
