Changing the size of the objects is as simple as resizing the window. To make the maximum use of the screen choose the Fullscreen option from the View menu.

To change the appearance of the objects use the Theme item in the View menu. Selecting an item from the list changes the theme immediately.

You can also create your own themes, although the process is not very straight-forward yet. Use a copy of an existing theme as a template and alter it with your favorite paint program. Put the result in $XDG_DATA_HOME/gnome-games/swell-foop/themes/2.10/. It will be automatically included on the themes list next time you run Swell Foop. $XDG_DATA_HOME is usually ~/.local/share/.

The Size menu contains three settings: small, medium and large. Aside from increasing the number of objects, the large setting also increases the number of different objects.

The default animation is designed to be smooth and graceful. If you like playing fast and furious then this may be too slow for you. By selecting the Fast Animation option from the View menu you can speed up game-play at the expense of animation quality.
