itch.io

I do have the app installed yeah, I used to have a Rift S myself. I tried switching between OpenXR and SteamVR runtimes and OpenXR prevented the game from even working (similar issue to someone else's comment I believe). I even tried disabling any plugins or add-ons in SteamVR too, nothing worked there. So you'll likely have to recode the game using Unity's SDK.

I'm using a Valve Index and when I open the game, I have no hands and the menu doesn't open. Might be some bugs in there that prevent the index bindings from working :(
