Help is just a prototype, but it’s already nearly perfect: in the American west of 1869, hunt down the bandits who’ve kidnapped your wife, then return her safely home. The controls are simple (walk around with WASD and point and click with the mouse to shoot) and the aesthetic and gameplay add up to an austere but thoroughly modern echo of Boot Hill. Sadly Windows-only.
UPDATE: It’s being expanded into a full game, titled Colt Canyon.
