Ok I found this post like a week late, but TikTok bought a VR company called Pico several years ago and they were investing money into new software and headsets, but recently cancelled all of their planned games. They are still making a new headset, but they also seemed to cancel their entry into the US market. They also had a ton of layoffs last year.
So basically, I think they’ve lost interest in VR.
osu! is a free and open source rhythm game. Its pretty much the best pc rhyrhm game.
