Shackwave is a local multiplayer arena game developed for #GGJ17
In Shackwave, your goal is to make other players fall from the arena pushing them with shockwaves that you can generate by clapping your hand or by stomping on the ground after a jump. Every single asset in the game was developed from scratch in 48 hours during the Global Game Jam 2017 in Milan.
The game is a local multiplayer game (up to 4 players) and works best with Xbox 360 pads. A single player mode is available.
