Did not even notice this game was on Kong. A tip, although a lot of people thing the hoops are the key to the game, they are not. The key is your landing (dive into the water) and your turn (when you spin around to leap back out of the water). The perfect landing is the easy bit, you must make sure the imaginary cord connecting the tail and the snout of the dolphin are as up and down as you can make them. The turning around is about feel, you get used to it and you will notice that if you get a good turn you will actually gain a huge amount of speed, in the high jumps this speed boost is actually faster than the hoops are!
Factory Balls 2 has a glitch, on any level where you have the āLā tool that makes things shiny, like a heat torch or something, if you screw up beyond repair you can just use the torch on the ball once or twice and it will be reset, without losing you a ball.
