Build a tower by timing your mouse click or key press to drop the swinging block. Lose a life for each block that tumbles.
There are a number of settings that can be adjusted but for most purposes the following two settings will be all you need:
Lives
The player loses a life each time a block tumbles from your tower. The default is 3 lives, this can be extended up to 20 lives.
Block Swing Delay
Slow the swinging block down by increasing the delay. The default is 100%, this can be increased to 1000% (very slow).
Only a mouse click or keypress is required to play the game.
