Quarry Climb
The Long Valley dig, an hour after the crew knocked off. Six storeys of timber staging run up the quarry face, hurricane lamps still burning on the rails — and up on the top gantry sits a feathered Therizinosaurus with a stolen egg tucked behind its claws. It doesn't care for climbers. Every few seconds it kicks another boulder down the plank ramps, so go up the ladders, hop what comes at you, and take the egg back. Clear five storeys and the Postal Society will postmark your own Quarry Climb stamp.
Left and right run along the staging, up and down climb a ladder when you're stood at one, and space jumps a boulder. On a touch screen, hold the side of the screen you want to move toward.
A boulder that meets a ladder head may drop straight down it, so glance up before you commit to a climb. Hopping one cleanly is worth points, and every storey you reach is worth more than the one below it.
