Mad Saw: Ninja Runner

A giant purple circular saw is rolling through a pastel paper world, chewing up everything in its path. You are a small round orange ninja with a headband, and the only way out is forward.

Mad Saw is a one-thumb ninja runner. You run automatically — you just decide when to jump.

NEW: SAW WORLDS
• 3 worlds of hand-made stages: the same layout every attempt, so every death teaches you something
• Instant retry: fall and you are running again in a blink, no menus
• Checkpoint flags in the later stages and up to 3 stars per stage
• A boss at the end of each world: the Big Saw, the Press Train and the Twin Saws
• WORLD OF THE MONTH: Haunted Sawmill, open to everyone from the first minute, with a Normal and a Nightmare boss
• Endless mode is still here for pure high-score runs

HOW TO PLAY
• Tap to jump
• Hold to jump higher
• Tap again in the air for a double jump
• Hit a wall in the air? Tap to wall-kick your way up
• Optional: swipe down in the air to slam through crates and stomp grumpy critters

Every bump, stumble or wrong jump lets the saw close in. You will hear it — the buzz gets louder, the screen shakes and your heart starts pounding. Fall into a pit or feel the teeth and you start again.

CHASE THE MULTIPLIER
• Red and cyan diamonds raise your ×N multiplier
• Chain pickups in the air for AIR COMBOS
• Stumble and the multiplier is cut in half — stay clean!
• Every metre counts: score, distance, full score, full distance and your best

POWER-UPS
• Magnet pulls in every gem nearby
• Shield blocks one saw bite (or bounces you out of a pit)
• Rocket blasts you forward over everything
• Slow Saw gives you a few seconds to breathe

SIX ZONES, NEW DANGERS EVERY 20 SECONDS
Paper Sky, Pastel City, Saw Factory, Night Run, Ember Works and Frost Peak — each with its own colours and music. The run speeds up all the time and the rhythm changes every 20 seconds: rooftops, spike gardens, machine lines, grump parades and climbs.
• The saw LUNGES: when it glows red, keep running
• Presses, flame vents, pop-up spikes, buzzsaws and rogue saws rolling at you
• Rammers that throw you back, conveyor belts, ferries over pits and floors that collapse behind you
• Greed gates: double points — but the saw gets angry
• Blackouts lit only by lanterns
• After every fall you see exactly what got you

AND MORE
• 8 secret escape rounds, including "The original": one jump only
• Daily rewards, lucky spin, missions and achievements
• Ninja colors in the shop, profile levels and Google Play Games leaderboards
• Revive once per run or start with a Rocket boost
• Works offline, no account needed

Can you beat the boss of world 3 — and how far can you run before the saw catches you?
