A companion collection to the Linux Gems collection. This collection contains games that have a Linux version elsewhere, is early in development or that we just haven't checked out properly yet. You might find something interesting here, but some caution is required, since many items in this collection don't come with Linux builds.
In development. Linux exclusive so far.
First I hear of it. Check it out.
Is being developed into a full game: http://www.rogueprocess.run/
Does it work?
