I've barely played it but I think it's quite interesting - it has a clean interface and runs on mobile. You can move your arms around as a desktopper/ phoneposter which is something you can't do in VRChat. Seems like there's some level of scripting in it too, based on the slot machine world we were just in. 

Doesn't seem to be that popular or well reviewed going by the App Store reviews though, and it seems to be JP first so I was seeing some pages in Japanese. I'd be curious to try to make a world for it - though I don't know if it's Unity
