Cosmic Express

- Drag to lay a single track that connects the train's start, stations, and the exit. - Pick up passengers at stations and drop them at homes that match their color or icon. - Plan the boarding and drop-off order; seat limits and one-way movement matter. - Avoid crossings and dead ends; refine the path until the train completes the route. - Use special tiles like portals or split tracks to navigate tight layouts when available. - Replay levels to find cleaner solutions and complete optional challenges or bonuses.
