Mindscape by jamesbragg (itch.io)
I've just completed this project for the end of my Fine Art degree so it is more an artwork than a game - or maybe an artgame. I've created a virtual world that you can wander about and filled it with objects that have meaning to me, so it is a bit like wandering around into my head.
The PC and MAC version have me telling you about things if you click on them, but I haven't developed that yet for the Quest - next planned step!
