About tri.Attack();
tri.Attack(); is a 2D arcade game inspired by classic Atari-era entertainment. You control a tri with powers that set it apart from other polygons: shoot it from your body to attack enemy polygons, then recall it like a boomerang.
Score and unlocks
Enemies award different amounts of points. Your score for each enemy increases when you defeat several with a single shot of your tri. Try to get the highest score possible and unlock all the tri variants as you play.
Tri types
- Normal: Your first tri is a good size and travels straight in the direction you shoot it.
- Triple: Three smaller tris travel in separate directions. You can shoot again once all three have returned.
- Follow: This tri homes in on your cursor, but recalls to you sooner than the other types.
- Sponge: It starts somewhat smaller and grows each time it hits an enemy. Its size resets when you recall it.
More tri types are included.
