Your task is to build the machinery that carries every passenger where they need to go. Across more than 100 levels, you put together chairlifts, gondolas, bridges and several kinds of ramp from a limited supply of materials, starting in gentle foothills and ending on exposed peaks. Rope tension and other forces behave realistically, and you also steer the passengers across the terrain, so how they fare is up to you.
Saving money by cutting corners makes construction cheaper but puts riders at risk, often with comic results. Single-player and darkly funny, it suits fans of physics puzzles and construction games who enjoy slapstick disasters.
