Stickman Archer is an endless arena-style fighting game that focuses on skill-based archery. The player attempts to kill various game-controlled fighters via a black silhouette-style archer that stands atop a floating platform against a light-colored background. Both archers hold black bows that feature red bowstrings and black arrows.
The player's goal is to kill as many opponents as possible by pushing each enemy archer off their platform with one or more precise arrows, the force of an arrow, or an arrow to the head. With each kill, a new archer appears in a different position than the last one. The player must align their arrows at new angles and adjust the force behind each one to take distance into account. If they're imprecise, they can overshoot or undershoot a target.
Stickman Archer provides the player with the means to gauge force and distance via a green horizontal bar near the top-left part of the screen. The player watches the bar fill up with a vibrant green color. Too little green, and the arrow falls short. Too much green, and the arrow might go past the opponent without hitting them.
