Fleabag vs Mutt

Fleabag vs Mutt (short name fleabagvsmutt) is a classic turn-based throwing battle Flash browser game created by Gametuner and released in 2000, widely shared on Chinese game portals like 4399. Players can pick either Fleabag the cat or Mutt the dog to fight. The cat throws empty cans and the dog throws bones. Gameplay is similar to Worms. Players take turns attacking. Hold the mouse button to charge power for the throw. You need to check the wind indicator at the top of screen to calculate trajectory. Hit the opponent to deplete HP; the character whose health drops to zero loses. It features single-player mode with three difficulty levels (Beginner, Average, Hardcore) and 2-player versus mode. There are four power-ups: double attack, power throw, stink fish bomb and bandage to restore health. With simple cartoon hand-drawn graphics and funny hit animations for pets, the game is fully mouse-controlled. It is a nostalgic Flash battle game for many players in China, and a beach sequel was released later.

These games get the keyboard directly — the controls are whatever the game itself defines, usually in its own help or options screen. Some games show on-screen buttons on phones.
