Ok I fixed it, try now!
I may have updated the game post-jam but honestly, it wasn't my fault! It's a weird bug in Godot or SteamVR where if the godot project name includes a question mark (Who's a good boy?) then the controllers don't work. WTF!?
This is literally the only change: https://gitlab.com/DanielKinsman/whos-a-good-boy/-/commit/9562d3360c2a51dc26888e...
