Contourfall: Terrain Puzzle

A quiet route-planning puzzle built from real contour logic: read slope, saddles, ridges, drainage, exposure, and limited stamina to guide expeditions home. Tap adjacent contour cells to draft a route and see cumulative cost immediately. Close contour spacing raises grade, fatigue, and descent risk. Ridges, saddles, streams, cliffs, and weather alter legal movement. Optional survey marks reward accurate elevation and bearing estimates. One hundred authored sheets, daily expeditions, and free-map mode are included. Everything shown is included in the paid download. There is no account, advertising, analytics SDK, subscription, external purchase, or server dependency. Work and progress stay on the device unless you explicitly invoke an Apple file picker or share sheet.
