This is a small VR-based game optimized for playing with popular HMD devices such as Oculus Rift, GearVR and Google Cardboard.
Turn on the sound on your computer or device because the audio is atmospheric. You can optionally use a gamepad connected via USB interface or Bluetooth instead of the mouse in order to control your space ship. You can also connect a web camera to check out how nice you look in a VR headset!
The game, of course, can be played without any headset too. If you are interested in how this all was done and/or want to create your own WebGL/WebVR game, check the source files both in the Blend4Web PRO and Community Edition distros.
