I was late playing with my kid, thanks for the info.
The path seems to be different in the latest ubuntu.
I will make changes to the source in the near future. Thank you.

I'm developing 1.4.0 for a commercial version of macOS.
If macOS update is complete, we'll be porting the Linux version as well.
