Looks like I'm another victim of the game not working.
It opens for a second, the console does it's thing, but once it says "ChainLoader Setup Complete," the game icon that appeared second earlier disappears from the taskbar.
I already tried using the tutorial provided here to add the game to the steam library, opened as admin, disabled anivirus, used Japanese localization, the 1.31 version also provided here doesn't work. I'm on Meta Quest 3. If anybody could help me with any idea of how to make this game work I'll be grateful.
