Shukran,
Yeah the controls are a bit all over the place...
This might help:
P1 Movement: Arrow Keys
P1 Actions: Left Ctrl, Left Option, Left Shift, Spacebar, (Up Arrow Key+Spacebar) for aerial move, press Tab to Block
P2 Movement: J(Left), K(Right), I(Jump), M(Crouch)
P2 Actions: Backspace Key, Enter, Right Shift, Right Option, press O to block
Let me know in case of any challenges...
