Cave flier for 1 to 6 pilots
Finnish for "hollow". Fly a V-shaped ship through a cave, shoot your friends, and land on striped pads to refill energy and swap your special weapon. First to the frag limit wins.

While landed, the Special key cycles weapons: missile, bomb, spread, mine, bouncer, laser, homing, shockwave. In the air it fires the chosen one. Land upright and gently. Esc pauses. Plugged-in gamepads also work: they take the pilot slots in order (A thrust, stick turn, X fire, B special). Keyboards can drop keys when many are held at once, so 5 or 6 on one keyboard is easiest with a few gamepads.
Ships, caves and weapons are all original to this game.
