I tried to install this using Meta Quest Developer Hub, and I think because the project name in the project settings is still the default, it isn't working. Here's the error I got: 
Edit: actually that message might be from Math Ninja because that won't install either. But yours still won't install so far. I'll try again in a bit.
Yeah it was Math Ninja they had the default project name. Going to try yours again later today
So actually it was yours, not Math Ninja. It took literally days, but eventually MQDH allowed your apk to be installed. And... passthrough definitely didn't work. And the cat was in constant jerk mode. Video of the cat
The settings menu looks cool and has lots of customizability. But nothing beyond that actually did anything at all. :(
I'd love to try this later if the core gets fixed!
Yeah there is still a lot of jankyness I need to fix. From your video it looks like the cat is colliding with some spatial data (as seen from the shadows it makes), but you're not getting the passthrough either. That spacial data may be from the test data that's in the project, but it should be replacing that with your own. Hmmm.
What are you using, Meta Scene API? MRUK? Or something else? In a previous jam (hackathon actually) I had been developing with MRUK which was great for developing and trying out different room meshes, but for the builds it just wouldn't trigger the Scene scan or use the on-device scene mesh. I never really got it figured out and had to ditch much of it and made a VR clicker game instead.
