Ronin Run is an action side-scroller where you play as a lone samurai running through dangerous territory. Your goal is to survive the run, defeat enemies, and reach the gate at the end of each level.

Use the left and right arrow keys or on-screen controls to move. Press the up arrow or swipe up to jump. Tap the attack button or press the spacebar to strike enemies with your katana. Time your attacks carefully — enemies approach from multiple directions and some throw projectiles.

Enemies that walk past you off the bottom of the screen will respawn from the top once, giving you a second chance to defeat them. Missed enemies count as points deducted from your score. When all enemies are defeated, the scroll speed doubles to bring the gate into view faster.

The level ends when you reach the wooden gate. Your samurai will automatically walk toward it for a cinematic finish. Try to defeat every enemy for the highest score possible.
