Welcome to CNET Australia's App of the Day, where you can see some of the coolest, silliest and most useful apps in action.
Every now and then, a game comes along that blows us away with its brilliant simplicity. Last Fish is one of them. A little glowing white fish swims along in waters, increasingly filling with black, deadly goo. You have to avoid the goo, collect the white orbs and complete challenges — surviving for as long as you can, collecting health points and swimming through an obstacle course. It's all painted in gorgeous monochromatic black and white, but it's the control system that blew us away; it's entirely tilt based, and every little shift of your phone moves the fish through the water. It's magnificently responsive and intuitive — tilt-based controls can be so hard to manage, but Last Fish has executed it to perfection.
