I saw an Oculus Go game in itch.io with instructions on how to sideload itch.io games into the headset. I'd love to see some game jams that allow Oculus Go games.
The go is a fantastic bit of hardware for certain, I personally love the one I was gifted as a part of Oculus Start, but having to sideload apps makes it a little offputting for some people. We could certainly look at hosting a Go or even general mobile vr specific jam in the future as personally I'd love to try my hand at a mobile project for the Go as well!
