About this game
You're a fish. Pearls fall out of the bottom of the platforms, and you must sort them by pushing them with your nose. If they fall off the bottom, they will loop back to the top. However, as you sort the pearls, the rate of pearl production increases. Don't let them pile up too much — they'll become harder to separate, and a wrongly-sorted pearl is -1 points. The game ends if a pearl stack gets too high and blocks a new pearl.
You can also play this game on your smartphone, by touching and dragging to move in a direction. As long as your finger continuously moves, the fish will move as well.
