There is not much to do in SW as of right now. Nonetheless, several people have expressed interest in seeing it as it is now.
Shadow Wolf has XBox controller support, but can be played with a keyboard without any problems. Controls are currently:
Keyboard:
Arrows to move
Space to jump
Z to attack
X and Z for specials
Controller:
Left Stick to move
A to jump
X to attack
Y and B for specials
Combos are executed by giving inputs in sequence. Most (though not all) characters can double jump by jumping a second time in mid-air.
Each character has their own set of combos and special abilities. Only Mitz is in a state where he would be even remotely playable in the actual game.
Hint: Mitz can super-jump by inputing Down-Up-Jump in sequence, and can do this even after a double jump to reach higher areas. There are currently no such areas to reach, but the ability is still present.
