This is a desktop pet game. He will stay on your desktop to keep you company, occasionally watching your mouse moving around.
You can beat him up using various moves, like pummeling him with the "Invincible Flying Fist". When you're frustrated with life or work, he is your perfect stress-relief punching bag!
You can also command him to dance.
You can summon a monster to eat him, or use a machine gun to chase him around the screen.
You can enter Zen Mode, striking a wooden fish to attain inner peace and accumulate merit.
As you progress through the game, you will unlock 30 different levels of achievements.
