Navigate a hollow planet.

Avoid lasers.

Collect alien artifacts.

Pilot your spaceship from the landing pad at the bottom of a mine shaft on a remote planet to the planet's surface. Pick up luminum crystals along the way that can be traded for upgrades, and if you’re lucky you’ll collect the parts of some alien artifact that are scattered throughout the caverns. But watch out for those mining lasers, and keep an eye on your fuel supply!

Cavernaut is a cave flyer, inspired by classic titles like Lunar Lander or Thrust, reimagined for todays mobile devices. Using smooth tilt & touch controls, you'll have to make it through 5 levels with increasing difficulty before you reach the planet's surface.
