Super Punchball!
About
2-6 players only! Controllers heavily recommended!
Super Punchball is a game created as a Kickstarter reward for Sportsfriends.
Xbox 360 controllers recommended!
Keyboard Controls
The game is not really playable with 4 players on the same keyboard. I'd recommend playing with 4 controllers (a lot of controller types are supported) or a few controllers and one or two players on keyboard. Here are the controls in case you really want to cramp it up on a single keyboard!
Player 1
[w, a, s, d] Move character (only for Joystick Mode)
[z] Action, Punch
[x] Back
[enter] Pause
Player 2
[t, f, g, h] Move character (only for Joystick Mode)
[v] Action, Punch
[b] Back
Player 3
[i, j, k, l] Move character (only for Joystick Mode)
[n] Action, Punch
[m] Back
Player 4
[up, left, down, right] Move character (only for Joystick Mode)
[delete OR mouse left click] Action, Punch
[end OR mouse right click] Back
