Background and Worldview: You are a young boy living in the giant steam-powered mechanical city of “Kazak,” with a “Gear Heart” implanted in your body—the city’s power core. The evil mechanical lord wants to dig out your heart to strengthen his war machines. You must traverse the city’s sewers, clock towers, factories, and aerial cableways to escape to the free wasteland outside the city.

Core Gameplay: “Steam Jet”—You can collect “water” and “coal,” mix them in your backpack to generate steam, and tap a button to launch the steam for a double jump or aerial dash. You need to manage the ratio of the two resources: more water results in a longer jet duration but less thrust, while more coal results in greater thrust but a shorter duration. You can also “overload” the steam engine (double the thrust but damage your equipment).

Features: Unique “Gear Terrain”—Some sections of the terrain are giant gears that rotate periodically; you need to step on the teeth at the right time to jump. Over 300 craftable steam devices (jetpack, spring boots, clockwork arms). Branching Story: Your choices affect whether different gangs are friendly or hostile towards you. Supports a “Spare Parts Market” for player-to-player trading.
