Dune Marble: sliding maze

A glass marble, a maze of sand and stone, and one rule: the marble rolls straight ahead until a wall stops it. Pick the swipes that lead it to every date, then to the exit.

HOW TO PLAY
• Swipe in a direction: the marble slides to the next obstacle.
• Collect every date in the level: the exit only opens afterwards.
• Finish with the minimum number of swipes to earn 3 stars.
• Unlimited undo, restart at any time, and a hint that shows the next optimal swipe.

10 DESERTS, 300 MAZES
Golden Dunes, Red Erg, Dry Wadi, Shifting Sands, Sinkholes, Mirages, Ochre Canyon, Ksar Alleys, Kasbah Gates and Dune Night: each desert adds an element and grows the grid (7×9, then 9×12, up to 11×15 with a camera that follows the marble).
• Soft sand: the marble stops right there.
• Holes: the marble falls and the level restarts, no penalty.
• Twin portals: the marble comes out the other side, same direction.
• One-way tiles: only crossed in the direction of the arrow.
• Switches and gates: roll over a switch to open or close the gates of its colour.

PROVEN LEVELS
Every maze was checked by an exact solver: the optimal number of swipes is known (from 3 to over 40), no date is unreachable, and hints always rely on a real solution.
