This was really great! I got it working on my Oculus Quest 2 with Virtual Desktop. I sometimes get motion sick with VR games that let you free move and there was none of that here! Very comfortable.
Some minor point which I'm not sure if they are due to your game or to Virtual Desktop or the Quest:
* I could not see any UI and never had any idea how much life I had -- Nevermind, I see now that it's the circle on my arm. If that was part of the tutorial, it would me great :)
* The combat is very easy. I was just about one-shotting everything, but the dragon in the end which took forever, and eventually killed me. It would have been nice to respawn at the start of the dragon level
* I couldn't tell what the square disks were, coins maybe?
Regardless, this was extremely impressive. The art is awesome and I'd love to see a full game out of this.
