Hi, I really love pirate solitaire. You can see the Zachtronics influence.
Two things I wish you would address:
1. Needs a native linux build
2. Support for arbitrary resolution (as mentioned in another comment)
Ooh! I spotted the link to the godot files and was able to do a native linux build myself :D.
For anyone else who wants native Linux, you can download my build from https://antisol.org/PirateSolitaire1.3_linux.zip
Enjoy!
