Build towers as tall as possible using springs!

Click mouse to place springs and try to avoid that the whole thing collapses.

Keys:

In menu:

• up/down to select level
• enter to start level
• esc to quit

In game

• arrow-keys to pan
• a/z to zoom
• q/w to turn on/off movement indicator
• 'r' to release all fixed joints (really only for fun)
• esc to exit to menu
• enter to restart

In short click mouse to create springs

Move mouse over existing active joint (orange joints have to be activated first) to select start for new spring

Move mouse to select existing joint for end of new spring or
select place for new joint as endpoint for spring. Basically, you can't create long worms (too easy to cheat).

The starting joint must be connected by at least two springs or be one of the predefined joints.

Orange joints are activated by connecting to them from an active joint

You have 5 min to build as high as possible, and height is only registered when building isn't moving, so it can be clever to sometimes stop and let the building settle to register it if it is close to collapse.
