I rarely give good reviews with a description just because I'm lazy. This game satisfied me to the point I needed to give it best score possible. That's why you read this. A little tip in the beginning will greatly improve your enjoyment. No further tip required since the game gives away a ton. Just don't be greedy for the initial tip and get your great white shark! It is 100% worthy!

great game over all, I enjoy both the 3d and 2d sides of the game. I wish the 2d fish puzzle game would stop lagging, and crashing the game out though.
