Publishing hearts game to Flathub

[FinixFighter]

Hi! I think that it would be great to publish this game as a Flatpak version! It would be so easy for Linux users to find it in their software center! Moreover, there's not aN hearts game on the Linux repository (at least I didn't find it on Linux Mint). This is the app submission wiki: https://github.com/flathub/flathub/wiki/App-Submission
What do you think? :)
