I have been working on this project on and off for a couple of years an finally finished a first full version, which I got compiled into a playable executable. I hope to find some play testers soon. It is not a game though.
It was developed under the working title Avant Garde VR (AGVR) which I seem to have kept it a secret as I posted only one blogpost on it so far, and that was four years ago, apart from this page on my website
I have just created a new project page
