• you can press the space bar (or type '2'), the element will fall straight down. If the height is sufficient (more than the half of the total height of the game area), this will prevent the game from speeding up.
• you can buy square blocks by pressing 'X'. This will fill the uppermost righter hole (i.e. a empty place where the next place up is filled).
• you can pause the game (a limited number of times, to avoid cheating…) by pressing '!' or choosing 'Pause' from the 'Run' menu. Note that the game checks how long you interrupt it (by dragging the game window, pulling down menus, using multifinder…). If the interruption is longer than 3 seconds, it considers that it's a pause !
• you can abort the game by pressing the escape key or choosing 'Stop' from the 'Run' menu.
