Description

AI generated by Codex for Shai. An original railway routing puzzle with five handcrafted routes. Rotate straight and curved track tiles to connect the left entrance to the right station while collecting two parcels. Includes animated train runs, disconnected track feedback, undo, a helpful track button and route completion marks for the current tab. Original SVG rails, parcel art and locomotive create a small model railway feel. Designed for phone touch controls and desktop keyboard accessible buttons.
