How do I fill the lower bar?
Now there are 3 bars in the game, the top one is the time, the bottom one is the warning and the bottom one is the satisfaction bar, you can press the sand right button so that the top one does not run out, it takes 20 gold to extend each stream. You can touch the nipple to fill the bar at the bottom, and as the heart on the side is filled, you can start to do more things.
