About Duck Samurai

Duck Samurai: Banana Bane is a 2D platformer. You play a sword-swinging duck making its way through four levels: Jungle Run, Vine Maze, River Rapids and the Boss Temple. Each level has platforms to climb, coins to collect and monkeys patrolling the ledges.

In the first three levels the goal is to reach the exit. In the Boss Temple you face the Monkey Overlord, who gets more aggressive as its health drops. Beat it to win the game. Your high score is saved in this browser.

How to play

• Move with the arrow keys or A and D.
• Jump with Space, W or the up arrow.
• Press X to slash with your sword. Each monkey you defeat is worth 50 points.
• Press P or Esc to pause.
• On phones, use the on-screen left, right, JUMP and ATK buttons.
• Coins are worth 10 points each.
• Spikes, water, monkeys and thrown bananas all hurt. You have 3 lives, and falling off the bottom of the screen costs one.
• The boss throws bananas at you, then starts summoning monkey minions, and in its last phase charges across the arena. A red glow warns you before each attack.

How it's built

Duck Samurai is built with Phaser 3 and arcade physics, loaded only in the browser inside a Next.js page. It has no image files: every texture is drawn with shapes when the game boots. The full story, including what AI agents did well and where they needed help, is in How I Built Duck Samurai with Phaser and AI Agents.
