Initially, the controls are the arrow keys to move and WASD to shoot. Press any WASD button to choose a direction, then press again to shoot. Press Space to switch those controls.
Changelog: April 10, 2019 - Remixed - Added "swap controls" button - Changed bullets to die when they a) hit a ship or b) hit the edge rather than c) go for 100 steps and die - Shared Plans: - Add settings screen to rebind controls - Settings screen to change aiming mode (e.g. with the mouse) - Add powerups (e.g. homing missile, or large laser)
