This game uses SteamVR, so you can play with 'Oculus Rift' or 'HTC Vive'.
To get controller input, it uses 'SteamVR Input'. 'SteamVR Input' is the system to customize button bindings and share those. It started in May of this year.
However, I don't have budget to buy 'HTC Vive', so I made a SteamVR Input bindings file for vive controller by text editor. Therefore, it might not work correctly. If vive controller doesn't work well, please customize that setting on your own or report errors to this board. I will fix it as soom as possible.
To open setting bindings page of SteamVR Input, first run SteamVR, then access this url (http://127.0.0.1:8998/dashboard/controllerbinding.html). (Settings of this game might not appear if you haven't run this game before.)
Default bindings file (This is the file I made) for vive controller is "bindings_vive_controller.json" in local directory of this game.
Below image is a bindings setting for Oculus Touch controller. If you want to modify a setting for vive controller, this will help.
