My Windows Mixed Reality Controllers don't work at all. They seem to want to emulate the Touch controllers, and I've made my own bindings, but none of them do anything. Normally they would emulate the Vive, but that isn't supported either. I'd love to actually play this, but it just doesn't work.
EDIT: Sorry, wanted to delete this, but I guess I can't. Just checked the Trello board, and instead of demanding an answer I'll just wait for a newer version. No worries.
