Hey, thank you!
Everything in APOTU is hand-crafted by me personally, 99% of it in Google Blocks : ). It’s kind of one of the pillars of the project.
Quest: don’t hold your horses! APOTU is secretly quite demanding (high-tier rendering and LOTS of physics) so it’s quite the challenge for a port. Not planning to for the moment, though I DID walk around in it on Quest via ALVR, which works surprisingly well!
