can you install this game from a quest or do you need a pc
You need a PC to install it and have your Quest in developer mode; but it is also available on SideQuest: https://sidequestvr.com/#/app/431; they have a tutorial on how to install non oculus-store software on the quest.
It may be possible to install from the quest, but you do need a PC to set up.
Use sidequest to install an Android apk installer, then you can use the quest browser to download apks to your quest and install them.
Ive only tested it with more traditional 2d installs (Discord to test) but I'd assume it should work with any apk.
