If you want to play QuestORama on a more beefy machine, I've just started up a PC-VR version of the same build. It's pretty easy, as the Unreal Engine can build between multiple platforms (yay Epic Games!). Since the Oculus Rift uses the same "Touch" controllers, you get the same game but at much higher framerates. I can also do neat things, like turn on shadows. I'm still trying to figure out the platform detection module, so I can keep the whole build using the same code, but a *slightly* tweaked Windows-PCVR version is available here:

It's v0.1.9. I'll TRY to keep it up to date with the Quest version. Right now it's tweaked with the, aforementioned, shadows, as well as a higher enemy count. Oculus Quest lags out from AI with more then 5 consecutive robots walking around at a time. To combat this, I spawn them as needed on the Quest. On the PC, they can pile up. So prepare for more difficult fights!
