Overview

About this game

This is a carefully designed desktop pet game. He stays on your desktop to keep you company, occasionally watching your mouse cursor move around.

You can beat him up with various moves—like pummeling him with the "Invincible Flying Fist." When life or work pisses you off, he's your ultimate stress-relief punching bag!

As you play, you'll unlock 30 different levels of achievements.

How to Play

Open the game and the little pet character pops up on your desktop.
When you're browsing the web or working on documents, he quietly stands in the bottom-left corner of your screen, occasionally turning to look at your mouse.
Left-click and hold to drag him—you can pick him up, and when you drop him, he does a roll.
Right-click to open the menu with various interactive functions.

Invincible Flying Fist: Generate fists from your mouse that fly toward your "little brother," attacking him non-stop at champion speed! Hit different parts of his body and he'll react differently—experience the thrill of punch-by-punch satisfaction!

Heavenly Fist: The fist of justice descends from the sky. You'll need to predict his running speed to land a blow. Hit him for double Kung Fu experience points!

Gatling Gun: Grab the machine gun and open fire! Execute him 100 times! Make him run all over the screen!

Summon Monster: Summon a monster. If he misbehaves, let the monster eat him!

Finger Flick: A light flick and he goes flying into the wall!

Zen Mode: Strike the wooden fish to find inner peace and accumulate merit.

The Right Way to Play

Your boss yelled at you? A coworker stabbed you in the back? Pretend your "little brother" is them and beat the hell out of them on your desktop with the Invincible Flying Fist.

Too agitated to focus on work? Switch to Zen Mode and strike the wooden fish at a steady rhythm. Your heart rate will gradually calm down, your concentration will return, and you'll enter a flow state.

Just won a game or hit the lottery? Switch to Dance Mode and let him celebrate for you!

If you're a streamer: when you tab back to your desktop after a gaming session, use this game to express your mood. Lost the game? Beat him up. Won the game? Let him dance. Feeling overwhelmed or guilty about all the virtual killing? Zen Mode will calm you down and help you accumulate merit.
