Troubleshooting
If the game does not appear in the Hollyhock launcher, verify that the .hh3 file is placed directly in the calculator root directory and not inside any folder. If controls feel unresponsive, ensure no other background processes are interfering with input handling. For persistent issues, consult the project repository or community channels for updates and compatibility notes.
