Voxel Fly VR is an arcade game in 3D that was specially created to be used with virtual-reality goggles, in which you control a tiny ship and have to travel as far as possible while you dodge vehicles and other obstacles.
In the beginning you only have one unlocked ship to use, but you can unlock the rest just by watching ads. One ad is enough to unlock one new ship, although they are only different in how they look.
In the settings of Voxel Fly VR you can activate the virtual-reality mode, which is optimized to work best with Google Cardboard or other similar devices. We highly recommend you try it. Not playing in that mode really lowers the game's quality.
Voxel Fly VR is a pretty mediocre spaceship game, but its support for virtual-reality is certainly a strength.
