Geometry Wars
Graham is recreating the (beautiful and addictive) Geometry Wars in canvas.
Best played with a twin-stick controller (or WASD + Arrow keys as a fallback)
If you’re on Windows, XBONE or XB360 controllers are the easiest to use. On Mac, a PS4 Dualshock 4 or wired 360 controller (with a downloadable driver) works well.
