HOP. STOP.
DON'T DIE!

The whole screen is your live canvas. Use the side rail to set lane types (Safe, Road, Water, Train) and add/remove lanes with + / −.

Select a WORLD THEME (Green, Factory, Fire, Ice, Space, City) from the dock. Tapping a lane applies that theme material to the lane instantly.

Select PROP and pick a World Theme. Tap an empty tile to place scenery, then tap that tile to cycle through props for your selected world theme.

Select MECH, then tap any lane. A popup appears above the tile showing every hazard mechanic available for that lane (Sink Carriers, Floor Drop, Flames, Slide, Zero-G, Blackout).

Tap 🦅 FLYING at the bottom to cycle background sky life (Birds, Cargo, Cinders, Gulls, Ships, Drones, None).

Hit ▶ PLAY at the top to test your course. Tap ✕ LEAVE directly below to exit — you’ll be asked to name and save or discard.

Toggle 👑 BOSS mode to build custom Boss Arenas. Pick your Boss Guardian (Greenland Guardian, Factory Press, Fire Volcano, Ice Leviathan, Captain Plot Hole, Showrunner).

Set floor surfaces (Void, Lava, Ice, Steel Grid), flame width, colors, second triggers, and arena hazard mechanics. Route validation ensures reachable carrier routes before saving!
