Attack on Mushroom vs Ninja Seeker Pixel

Dodge spike balls to protect the mushroom!

They're right behind those paper doors. Can you spot the tell? Ninja Seeker is a retro pixel arcade game about one simple thrill: spot the hidden ninja, throw the shuriken. Enemies hide behind Japanese paper doors — the only tell is a door pushed up ever so slightly — and a sliver of a foot peeking out beneath. Aim, throw, THUD. EASY TO PICK UP - One round takes about 30 seconds — perfect for a quick break - One finger, one motion: tap the door, smash the ninja - Plays offline, no ads, no account needed SPOT THE TELL A door hiding a ninja rises just a little: obvious on Easy, a mere 1.5 pixels on Hard. Train your eyes, trust your instinct, and strike before time runs out — every hit lands with satisfying haptic feedback. DEPTH WHEN YOU WANT IT - 9 ninja arts: shuriken, bomb, fire, poison, water, ice, wind, thunder — plus a screen-clearing Fuma Shuriken ultimate - Climb the castle: 110+ handcrafted levels across 4 floors, then an endless mode that never stops scaling - 5 boss masters, each a different duel: clone-spotting, hide-and-seek, memory bombs, bullet hell, and a rhythm sword duel set to Beethoven's Fate Symphony - Conquer the castle keep to unlock Advanced Challenges — all five masters, remixed and harder - A story told in manga-style cutscenes, a codex of characters and lore, and detailed play stats FAIR & SIMPLE The full game is free. One optional one-time Premium unlock (no subscription) gives you every ninja art from level 1 with extra ammo, a free ultimate every stage, and boss practice mode. That's it — and no ads, ever.
