I just released my Free Demo on Steam. Developed and runs on Linux.

I was able to get the Linux build running this morning for the first time on Steam. It was running via the Steam Launcher on Mint Linux. I can't guarantee that it will run on your distro.
Please check out my game.

It contains quite a few rogue-like features:
Procedural Map Generation
Hunger
Encumbrance
Factions
Complex Combat
