The trail
A mountain goat has taken over the ridge above the trail, and it has a habit: it kicks rocks down the slope. Lots of rocks.
You’re the trail crew, with a stack of three rescue sleds. Slide them along the trail and catch every rock before it lands. Any sled in the stack will do.
Drag anywhere on the screen to slide the sleds: your finger never has to cover them. Tap to start each wave.
Every wave is longer and faster, and each rock is worth more. Miss one and the rest of the wave comes down at once: you lose a sled, and the goat starts you a wave back.
Every 5,000 points (before the slope’s multiplier) earns back a lost sled.
Catch every rock. Every one.
