About the Game
Bad Triangles is a fast, side-scrolling space shooter that runs entirely in your browser. You pilot a lone ship across a hostile alien asteroid field, blasting waves of geometric enemies, dodging hazards, and surviving until the boss arrives at the end of each level. Clear a level to move on; there are ten in all, and enemies and bosses get tougher as you climb.

Hazards
- The boundary lasers. A glowing laser runs along the top of the screen and another above the asteroid surface at the bottom. Touch either and you lose a life, so stay inside the playfield.
- Enemy ships. Enemies fly in and fire back. Their fire rate and bullet speed increase after level one.
- Comets. Every so often a comet streaks across the screen. It destroys your ship and enemies alike, and if it hits the ground it explodes in a wide blast.
- Bosses. Each level ends with a boss that soaks up many hits. Beat one while still alive to earn an extra life and advance.
Tips
- Keep moving. A stationary ship is an easy target for both enemy fire and comets.
- Watch for a comet's glowing trail before it reaches you.
- Grab floating power-ups when it is safe; the extra-life pickup is worth a detour.
- Your best scores are saved on your own device, so try to beat your personal top five.
