Iron Turtle

You control a small, metallic turtle. Your goal is to guide it through each single-screen level to reach an exit door. Movement is direct; you use the arrow keys to run left and right and to jump. The challenge comes from navigating the environment. You bounce on springs to reach higher platforms, and you must carefully time your movements to avoid spikes and other stationary hazards. The game has a steady pace. It's not frantic, but it requires precision, as a mistimed jump will send you back to the start of the level. Playing it feels like solving a small, physical puzzle with each attempt.
