Your mapping is beautiful, your environment is fantastic! For some reason I was getting a bit motion sic and I don't have problems with motion sickness anymore in games, so..not sure why. Anyway I got to the part with the neural head band but I couldn't put it on my head. Also, sound was missing. I thought maybe you didn't have time to add but someone else mentioned it in their comments so maybe its bug I'm running Oculus cv1.
Overall its a beautiful game, the visuals are fantastic.
Here is a link to the game I worked on.
