Press anywhere on the screen and drag to move Dudu; let go and Dudu stops. There's no attack button: your weapons fire on their own. Pick one of eight outfits first. Each starts with a different weapon: Knight slashes, Wizard shoots stars, Archer throws feathers, Chef lobs mooncakes, Astro has orbiting moons, Ninja calls down lightning, Witch plants poison flowers, and Hanfu Dudu carries a lantern glow that burns anything close. Defeated monsters drop gems. Grab them to level up, then pick 1 of 3: a new weapon, a level for one you already have, or a charm (more HP, speed, damage, faster cooldowns, bigger pickup range and more). You can carry six weapons and six charms. Elites drop a treasure map for a free upgrade, and you'll also find dango (heals you), a moon eye (pulls in every gem) and firecrackers (hit everything on screen). The monsters change every minute. Elites show up along the way, a Mountain Ogre at 3:00 and the Moon Nightmare at 6:00. Survive until 7:00 and the sun comes up; beat the Moon Nightmare first and morning comes early. A run takes about 5 to 7 minutes. The button at the top left pauses; music and sound effects can be switched off separately on the start screen or in the pause menu. Your best time and kill count are saved on your phone. Dudu, the monsters and the item art all come from the sprites in the Y Build app. Sound effects are also from the app. The cover illustration was generated with AI using the game's sprites as reference, and the background music was generated with AI.
