Dear Maxalo. I downloaded the Pre-Alpha Demo 1.6 to see if it's a game i can "stomach" or not :-)
I can start the game alright, the hands show but am not able to activate any of the options, skip/start buttons etc. Trying to set bindings in SteamVR is more challenging than programming a VCR clock.
Then I saw that your game does not mention WMR headsets. I use a HP G2 Reverb with inside out tracking motion controllers. So, i guess it's not compatible with WMR, rght?
