The KFoulEggs configuration is accessed from Settings->Configure KFoulEggs. The options are as follows:
Set the level which you will play at startup, from 1 (easiest) to 20 (hardest). Default is level one.
If checked, a shadow is placed beneath the game board showing where the piece will fall.
If checked, shows the next tile that will fall onto the game board.
Sets the size of the falling blocks.
If checked, pieces gluing are shown with an animation.
Controls the fade balance between the desktop background and the KFoulEggs background. A setting of zero makes the KFoulEggs background completely transparent, and a setting of one makes the KFoulEggs background completely opaque.
Displays a dialog allowing you to choose the colour of the KFoulEggs background.
