+Dragging a colour using the \e{right} mouse button will stipple the

+stipples in multiple colours at once. (This is often useful at the
+harder difficulty levels.)

+If you press L during play, the game will toggle display of a number

+by names such as \q{the one down and right of the brown one on the

+
+You are a small green ball sitting in a grid full of obstacles. Your
+aim is to collect all the gems without running into any mines.
+
+You can move the ball in any orthogonal \e{or diagonal} direction.
+Once the ball starts moving, it will continue until something stops
+it. A wall directly in its path will stop it (but if it is moving
+diagonally, it will move through a diagonal gap between two other
+walls without stopping). Also, some of the squares are \q{stops};
+when the ball moves on to a stop, it will stop moving no matter what
+direction it was going in. Gems do \e{not} stop the ball; it picks
+them up and keeps on going.
+
+Running into a mine is fatal. Even if you picked up the last gem in
+the same move which then hit a mine, the game will count you as dead
+rather than victorious.
+
+This game was originally implemented for Windows by Ben Olmstead
+\k{bem}, who was kind enough to release his source code on request
+so that it could be re-implemented for this collection.

+You can move the ball in any of the eight directions using the
+numeric keypad. Alternatively, if you click the left mouse button on
+the grid, the ball will begin a move in the general direction of
+where you clicked.
+
+If you use the \q{Solve} function on this game, the program will
+compute a path through the grid which collects all the remaining
+gems and returns to the current position. A hint arrow will appear
+on the ball indicating the direction in which you should move to
+begin on this path. If you then move in that direction, the arrow
+will update to indicate the next direction on the path. You can also
+press Space to automatically move in the direction of the hint
+arrow. If you move in a different direction from the one shown by
+the arrow, the hint arrows will stop appearing because you have
+strayed from the provided path; you can then use \q{Solve} again to
+generate a new path if you want to.
+
+All the actions described in \k{common-actions} are also available.
+In particular, if you do run into a mine and die, you can use the
+Undo function and resume playing from before the fatal move. The
+game will keep track of the number of times you have done this.
