Ninja Sprawl
Read full descriptionHide full description
The original Ninja Sprawl first hit the App Store in February 2012. Fourteen years later it's back, rebuilt from the ground up: 160 tiny, deadly levels, a ninja who can stick to anything, and a clock that never stops. RUN. JUMP. SPRAWL. Run, jump and wall-jump, then SPRAWL: spread out to glide, cling to walls and ceilings, brace across shafts, swing from rings and ride zip lines. Simple to pick up, endlessly deep once you start chasing time. 160 LEVELS. 10 WORLDS. The Dojo, Bamboo Grove, Edo Rooftops, Frozen Peaks, Clockwork Keep, Volcano Shrine, Neon City 2099, Robot Factory, Ghost Temple and Sky Fortress. Each one brings new tricks: crumbling floors, springs, teleporters, switches, saws, lasers, rockets, snipers, lava and more. BEAT THE CLOCK Every level has a clock. It drains while you play, every gold adds time, and when it hits zero, so do you. Die, and you're back at the start in under a second. CHASE THE S RANK Three stars on every level: finish it, grab every gold, beat par. Then race the dev's own time for an S rank. Your best run plays back as a ghost, and you can watch the dev's route when you're stuck. A NEW GAUNTLET EVERY DAY Five levels in a row on one clock, the same five for everyone. Post your time on the daily Game Center leaderboard and race your friends. MARATHON A whole world on one draining clock. How far can you get? DRESS YOUR NINJA Bands, hats, tails, trails and ink in the Dojo, most of them earned by playing. CONTROLS YOUR WAY Big on-screen buttons you can resize, fade and swap for left-handed play. Keyboards and game controllers work too. Game Center leaderboards for the daily gauntlet, every world's Marathon, total stars and more, plus 18 achievements. No ads, no energy, no account. Free to play: every level, every world, every mode. Shuriken, earned by playing or bought, buy a continue when the clock runs out, a bigger hourglass, skips, the dev's route, early worlds and looks. They never buy a rank. The Ninja Pass and the Style Pack are optional one-time purchases.

Verdict
The clearest difference is update cadence: Crazy John at every 4 weeks against Ninja Sprawl's every 3 months. Crazy John also leads on iOS requirement (3.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
