Zabuyaki is an old-school side-scrolling beat 'em up.
It is free, open source and cross platform.
The game is far from finished, but you can still try it now!
Just install LÖVE (version 0.10.2) then run Zabuyaki.
Player 1 controls: X = Attack, C = Jump
Some game pads are supported, but touch screen is not.
