Indian Outlaw

You control a lone warrior fighting through waves of enemies. The moment-to-moment play is about movement and shooting; you use the keyboard to run left and right and jump, while aiming and firing with the mouse. Your main goal is to survive each stage, clearing out all the opponents to progress. You can switch between different weapons, like a bow and a rifle, and there's a special attack you can trigger for a moment of advantage. The pacing is fast, and the difficulty comes from the sheer number of enemies that come at you. It feels like a constant, hectic scramble to stay alive.
