Zaag is pretending to be a lost 1980s vector arcade game. Blast the zoids and cleanse the Tau.
As an arcade game, Zaag of course asks you to dodge and blast enemies. Classic arcade difficulty.
Your blaster has an initial charge up time, so focus on staying alive at the start of each Tau. Look at the tail of each zoid to get an idea of their speed and direction. Your tele is ready immediately, but has a long cooldown.
If using a game controller, use the D-pad instead of the joystick. You don't want to hit tele or flip by accident.
Zaag supports two-player co-op. Enable two-player mode at the title screen by pressing any key on controller 2. Look out for friendly fire!
Zaag uses the built-in gif recorder to save instant replays of your deaths (in the pause menu). The Pico-8's gif-maker is amazing—I'm surprised every game isn't using it.
