If you prefer playing with mouse&keyboard in vr then you can toggle a seated mode in options. It removes controllers and snaps camera to bold's head. Having issues with navigation in menus with controller? Known issue, wait for fix. Wanna play with mods? Drag mod files from Steam\steamapps\workshop\content into LocalLow\Naelstrof\KoboldKare VR\mods folder.
I just lost motivation to work on this mod. Plus I had to close my Discord messages for almost a two years because of certain group of peoples from game's official Discord server. No fun.
