Did you try it? It is still in development, so not final at all. It is also a prototype to show the technical aspect of the game. We'd love to polish and develop the game with community feedbacks!
It would be nice if the the game would actually work. So we could try it. P.s.: using vive here. And after the menu all you can observe is the white nothingness. Nice!
The game can be played both in VR and non-VR. Currently it is for PC only. There are Q&A in README file, so if you encounter any error please refer to it. Let us know if we can support further.
