Gruff: Goat Climb

Gruff is a mountain goat with a problem: the troll at the top of the mountain has caged his herd. Pull back, judge the leap from a few dots of arc, and let go. Land all four hooves dead centre for the clack, the bonus and a growing streak. HOW IT PLAYS • One thumb: pull back anywhere and let go to jump. There's no power meter. You read the gap and trust your aim. • Dead-centre landings build a streak and the points multiply. Miss the edge and Gruff hangs on by his front hooves, so tap fast to haul him up. • A rising avalanche chases you from below, so keep climbing. THE TROLL'S MOUNTAIN • Five zones, each with something new: the Meadow, the Scree, the Snowfield, the Ice Wall and the Summit Storm. • Reach a new zone to free a goat from Gruff's herd. • Dodge boulders the troll rolls down, a rival ram, a swooping golden eagle, marmots and a prowling mountain lion. • Ride steaming geysers, bouncy moss, swinging logs, tipping ledges and tiny pinnacles. PICK-UPS AND PERKS • Grab Golden Horns to send a boulder back at the troll, plus a feather, a helmet, a cowbell, a snow fence, a climbing rope, crampons, a lucky clover and a trail map. • Rest at cairns to pick a perk like Sure Hooves, Keen Eye or Long Legs, and level it up when it comes back around. Hand-drawn pixel art, acoustic folk music and real recorded sounds. Runs last a few minutes, so it's quick to pick up and hard to put down. Free to play with a small banner ad. No account needed. Your progress stays on your phone.
