This is a 10 stage game where the object is to push the blue block onto the blue spot of bricks. Trickier than it sounds. Brown blocks can be pushed unless there is no where for the block to go then the block breaks. Gray blocks can be pushed but cannot be broken. All blocks will fall straight down. Flappy (the character) can move in any of the four directions freely. Mushrooms can be collected and thrown to put serpents to sleep. If Flappy is squished, hits a spike, or the serpent bites him then the stage is restarted.

Arrow keys move Flappy. Move Flappy against a block to push it or break it. Use the space bar to throw mushrooms (give yourself plenty of room to toss).

Note: the game's menus are in japanese as is the help file. However, with a little fiddling around, the controls are pretty simple to understand.

Finally, to uninstall, use the Add/Remove Programs applet in the Control Panel to uninstall Flappy (it appears in the list as FLAPPY WORLD).
