About Katana Flash: One-Button Ninja Action Across 100 Stages
Katana Flash is a one-button ninja action game drawn in ink against a sunset sky. A spinning aim line does the aiming for you — the only decision is when to tap. Get the timing right and your ninja dashes along that line, cutting down every enemy in the path. That single mechanic drives the entire journey: 100 stages spread across 10 regions, each region capped by a boss fight and introducing a new enemy type.
Several scenes show the ink-on-sunset visual style in action, with bold silhouettes and brushwork giving the game a distinct hand-drawn character.
Beyond the stages, a Dojo offers daily challenges and endless waves, while a ninja village with five buildings — each upgradeable through 10 levels — gives a persistent layer to the experience. Ten katanas alter how the dash itself behaves, and eight costumes let you change your ninja's look.
How to Play Katana Flash
The aim line spins on its own. Tap, click, or press Space the moment it crosses enemies, and your ninja dashes along it, cutting everyone in the way. Dash directly into arrows to knock them back at your enemies. Clear every wave in a stage to complete it, and defeat the boss that appears every 10th stage.
Enemy Types
- Archers whose arrows you knock back
- Shield bearers you cut from behind
- Bombers
- Ghosts
- Chained twins
Katanas
- Wall bounce: changes the dash to bounce off walls
- Double dash: changes the dash to dash twice
- Slow time: changes the dash to slow time
- Ink trail: changes the dash to leave an ink trail
Ten katanas in total are available to forge, each altering the dash in its own way.

Rebuild your ninja village across five buildings, each with 10 upgrade levels. Stages award up to 3 stars, and 10 katanas can be forged. Eight costumes are available to unlock alongside the village progression.
