This VN probably doesn't need another platinum ranking since Valve has whitelisted it, but I figured this would be a good place to share that if you want to use the Steam Improvement Patch , you may want to avoid the Flatpak version of Steam. In that version, the game crashed for me after starting the came through the launcher once you've told Proton to use the version of dinput8 included in the game patch, which you need to do in order for the patch to work. As others have indicated, the patch works really well with the regular version of Steam, although I did have to use Proton 5.0 instead of the default of Proton 3.16 for this game in order to use winecfg to use the correct dinput8 DLL. Otherwise the winecfg GUI wouldn't open and Proton complained about missing some OpenVR file.
