Your score is based on how quickly you finish a room. The faster the better!
You may get bonus points when you slide into a Bonus block.
You can "take back" moves in a level, select "Undo Move" from the edit menu or hit command-Z.
WARNING! You LOSE 100 points for each Undo you do!
Note: Undo might not always bring you back to the *exact* same configuration.....
When you finish a room, Slider will count down your points rapidly on-screen. To make it go even faster, hold down "command". To skip the countdown completely, hold down "command" and "option"
