I would hereby like to introduce you to a contingent resource of free and open-source games for Linux:
LucKey Productions, a game development cult that is mindfully zealous about FOSS.

The cult's primary goal is to create free and open-source games and tools using only free software. Beyond that the aim is to open LucKey Orifices around the world where people may walk in and exchange their knowledge concerning free and open source software. LucKey Devels could meet here to progress the cult's many projects meant to liberate the industry and entertain the liberated. If you can spare coin to further this vision of free-flowing development your kind donation will be met with utmost gratitude.

Currently there are three games available through itch.io:

• heXon


• Quatter


• A-Mazing Urho

The first is a twin-stick-shooter that can be played with four players, the second is a board game for two players set in a calming environment. A-Mazing Urho is a maze rhythm game which started out as a jam entry.
I'm also really excited about these - as of yet - unreleased titles:

• KO and the Curse of Greyface


• Blip 'n Blup: Skyward Adventures


• OG Tatt


• Masters of Oneiron

On GitLab you can see what else is in the pipeline. I hope you like the results so far and that you may water the seeds if you do.
