You are Dudu, fighting your way through the Mushroom Forest. Drag anywhere on the left half to move, and tap the fist to punch: the third hit launches them, and if you jump after it you can keep hitting in the air. Around the fist are five skills: Spin, Wave, Roll, Throw and Slam. Hold Spin, Wave or Slam to charge them. Some skills chain into combo moves: Roll right after a Wave and you become a fireball. Dash right as an attack is about to land for a perfect dodge, and your next hit is a guaranteed critical. Every monster needs its own trick: burrs prick your fists, mushrooms puff sleepy spores, jellies split in two when hit hard. Hits fill a star; when it glows, drop from the sky as the Dudu ultimate. After three waves comes the Stump King. Play it sideways: if you hold the phone upright, the game turns itself, so just tip the phone to the left. Dudu is the hand-drawn character from the Y Build app; Dudu's moves were made by an AI video model from that drawing. The monsters, the forest and the effects were drawn by AI, and the sound effects and music are AI-generated. The button click is from Kenney (CC0).
