An Owl's World is a 3D platform game about a small voxel owl and a very long way home. Steer with the left joystick, tap JUMP to cross the gaps, and hop from island to island across a sky full of floating worlds. A CAMPAIGN THAT KEEPS GROWING HARDER Twenty chapters and 150 courses take you from the wide, friendly islands of The Floating Forest to the brutal Nightmare chapters. Each chapter adds something new: drifting platforms, crumbling ledges, orbiting crystals, twin fireballs, lightning, and spinning cogs. Later on, sentries fire aimed bolts, drifting clouds hide your next landing, timed crushers slam down, low lasers sweep the ground, and gust zones push you off course. Learn the timing, find the safe line, and reach the glowing arch. SHIELDS, FLAGS, AND SECOND CHANCES Every attempt starts with three shields. An obstacle hit costs one and knocks the owl back. Run out and the attempt ends. Flags save your position along the way, so Try Again puts you right back at the last flag instead of the start. ENDLESS MODE Chase a high score by jumping onto as many new platforms as you can. One fall or one hit ends the run. How far can you go? FIREFLIES AND FRIENDS Collect fireflies on every course and spend them in the shop. Unlock new characters to play as, including Pocket Penguin, Canopy Monkey, Ember Fox, Mossy Frog, Pookie the Maltese, Ted the Bear, Peanut the Capybara, and Tuck the Chihuahua. Grab the Extra Shield power-up to start every attempt with four shields, or trade fireflies for extra lives. LIVES You start with five lives, and one refills every 30 minutes. An optional Pro upgrade gives you unlimited lives. PLAY YOUR WAY - No sign-up required. Tap Play and go. - Sign in with Apple to keep your progress and purchases across devices. - Built for iPhone and iPad, portrait and landscape. - Haptic feedback on every jump. - Music is off until you want it. Tap the speaker to turn it on. An internet connection is needed to start a run, shop, and sync progress. A run already in progress can be finished offline. Ready to fly? The islands are waiting.
