Celtreos

One or two players. Use a mouse or trackpad, keyboard (including Touch Bar), or 1-2 game controllers.

Steam version works on Mac (available for mobile and TV elsewhere); updated with support for all recent Mac hardware.

Celtreos is like the space shooters of decades past: tiny ship, big weapons, waves of foes, power-ups and obstacles.
