TublerVR WebEdition can be played at: https://www.siliconwetware.com/#webvr
The WebEdition demo level is made for WebVR (the experimental side of VR :-). Which means you can play it in your browser (Firefox) without an installation. Of course this also means lower framerate and quality compared to the full version, but it will give you a first glimpse at the game.
Hope you enjoy
