Hey Jim,
Where exactly are you seeing these version names?
The Download page on itch.io lists "Version 20" in grey font underneath the first two downloads for 0.7.12, and "Version 14" underneath the third download for (Android) 0.7.12. I didn't even notice those until I saw this comment, though. I guess the "Version X" stuff is probably some versioning system that itch.io handles, or something?
