Hello and thanks for the report. Are you using Windows or a different system?
Hello there, a Linux-gamer here.
Gotta report something similar. As far as I understood, the game should run after clicking "RoyalOrderExtendedDemo.sh". By default, it doesn't as it's missing the executable flag (addable by running "chmod +x RoyalOrderExtendedDemo.sh" in the folder where the file is located).
After that, you get bonked by "lib/py3-linux-x86_64/RoyalOrderExtendedDemo: Permission denied". Also fixable by running "chmod +x lib/py3-linux-x86_64/RoyalOrderExtendedDemo".
Mind adding that stuff to the download-and-install instructions?
Thank you.
By the way, this game is fricking great and awesome and I totally didn't not get addicted for those couple of hours of visual novel in the extended demo.
