Tap left for Mox, tap right for Nib, and keep both friends hopping at once. A two-thumb arcade challenge built for iPhone Duo. No ads, no tracking. Two odd souls. One great escape. Mox & Nib is a two-thumb arcade game. Mox hops through the sunlit ruins of Clockwork Grove while Nib hops through the moonlit caves of Dream Hollow, side by side, at the same time. Tap the left side of the screen to make Mox hop. Tap the right side to make Nib hop. Dodge every obstacle in both worlds to score. It sounds simple. Then your thumbs start arguing with each other. HOW IT PLAYS • One thumb for each character, both running at once • Every obstacle you clear in either world adds to your score • Miss in one world and the run ends, so watch both sides • Quick runs that are easy to start and hard to put down • Your best score is saved on your device, so there is always a number to beat TWO DREAMY WORLDS • Clockwork Grove: golden ruins, old gears and overgrown arches • Dream Hollow: moonlit stone bridges, glowing mushrooms and crystal caves • Original characters and an original chiptune soundtrack MADE FOR IPHONE DUO On iPhone Duo, open the inner screen and both worlds sit side by side on one big display, one thumb on each half. Folded, the outer screen keeps the same simple left and right controls. Mox & Nib also plays on iPhone and iPad. FAIR AND SIMPLE • One-time purchase. No in-app purchases. • No ads. • No tracking, no accounts and no data collected. • Pause any time, and mute the sound and haptics with one tap. • Supports Reduce Motion. Can you keep both of them hopping?
