This little game was our project at global game jam 2017. The theme was "waves".
Push your friend around in this 2-player twin-stick shooter. Use different sound waves to force your opponent into deadly lasers and spikes. There are two wave frequencies, a fast but small one, and a slower wide one - special is, if the same waves hit each other they dissolve! Requires 2 controllers on PC or Mac. Left stick to move. Right stick to aim. Left trigger to switch weapons. Right trigger to fire. First to score 20 points wins.
