Latest word from the world of apps says that Cut the Rope, a 99 cent app for iPhone and $199 app for iPad, has just passed the two million downloads mark. By all accounts it’s an addictive app, which is the most desired trait of an app. Players always want just one more game. Then comes the “Holy Guacamole” moment about two hours and tons of games later. Where did the time go? In any case, Cut the Rope features a green, but not necessarily green-eyed, monster named, Om Nom. Om Nom is a baby monster who loves candy. But the candy is dangling precariously on a string above Om Nom. Your mission, should you choose to accept it, and you will, is give the baby some candy. To do this, you would use your physics knowledge to cut the rope so that the candy will swing low, and close enough to Om Nom to be devoured. The game was developed by a small team of mobile app developers in Moscow who call themselves ZeptoLabs. But Cut the Rope was not their original idea. Another game called Parachute Ninja featured similar elements of rope-swinging. When the game seemed to be excessively complex, they recycled the “physics-engine” aspect of it. Who would have guessed? Apparently we only love our mobile apps if the science is simplified. In the world of apps, there are developers and publishers. Cut the Rope is published by Chillingo, the same people who published Angry Birds which was developed by Rovio. But now Rovio is self-publishing while Chillingo is owned by Electronic Arts. Rovio just released Angry Birds Halloween which sold a million downloads in about six days. Meanwhile Chillingo wants to publish your addictive, physics based app – if you’ve developed one.
