I'm developing the game Exodemon and yesterday we launched it's Steam Greelight page.
Its a fast paced FPS game, highly inspired by classics like DOOM, Hexen, Quake and Heretic.
It's not a clone in any way, but I use a lot of what I learned from the masters in this game.
Well, here is the greelight page, please vote yes if you like the game
And here is the itch.io page
