Twin Treads
Two line-drawn tanks in a maze that changes every round. Your shots bounce off the walls, and so do theirs. First to five round wins takes the match, then the next CPU is sharper.

- P pauses.
On touch
- On-screen buttons turn, drive and fire.

Every run starts on the title screen. Pause any time with P or the pause button; calm mode removes flashes and screen shake.
Maker’s note
Ranked runs are always you against the seeded CPU. A round win pays 100 plus 25 per match already won plus a speed bonus; a match win pays 500 times the match number plus 60 per round you did not lose. Lose a match and the run is over. Mazes, spawn spots and the CPU's aim wobble all come from the run's seed, so a daily is the same maze sequence for everyone. Two-player games are never ranked.
