Drag the wriggly worms around the maze until you can release
the blue wriggler through the light-blue gateway. You can drag
by head or tail and it does not matter which end exits first
(the head is marked with eyes, but this is entirely cosmetic).
Use the puzzle drop-list to select a puzzle.
Use restart (action) or the space key to reset.
Use the mouse to drag the wrigglers by their head or tail.
