Nice game! Huge fan of the Zachtronics solitaire games and this is a really fun variant that isn’t too hard, a pleasant level of difficulty for a quick phone game. I found it on F-Droid and was pleasantly surprised to find it an open source Godot project. Thanks for your efforts!
Edit: btw just read some of the devlog, in case you didn’t know 4.2 will support C# android builds if that is your language of choice:)
