You can't. This game requires a capable PC and Oculus Link cable, which the Quest 2 does not come with. So no, PCVR only. From what I've heard, Virtual Desktop works, but is very laggy.
He made the game with the help of his quest. It is laggy because Oculus Link is in beta, but still playable.
Link just got out of beta, and I believe it may be your hardware, I get a smooth 60 usng the included charging cable.
