I commend the attempt to bring together a lot of fancy tech for this, though it might not make for the best game ;) Having fallback, uh, mouse support would probably bridge the gap for those without all the hardware.
I tried it out on a Mac M1. Seems like the hand detection is a bit finicky (though I see from the demo video that the hand is moving sloooowly) -- so I tried being slow and trying various lighting conditions too. It's very good at only responding to my right hand. In the limited time I tried, the virtual hand position seemed to jump all over the place so it was difficult to hit the X on the Tutorial page. Once I got that bit working, it was similarly a chore to "catch" a rat. But, once that was achieved, catching cheese was a bit easier, though the time limit is quite short :).
