The aim of the game is the same as before. Om Nom sits at the bottom of the screen, and somewhere above is a piece of candy, tied up in a precarious position. All you need to do is cut the ropes (with a swipe of your finger) to start the candy moving around the screen. The primary goal is to get the candy into Om Nom's mouth, but on every level there are three stars, and for bonus points you can swing the candy piece around to collect these stars before being feeding Om Nom.
From the directory listing:
The little green monster Om Nom is back and hungrier than ever! Team up with the Professor, a mad (but not bad!) scientist determined to study Om Nom’s candy-loving behavior through a series of experiments. Use suction cups and other funny devices to collect shiny gold stars, uncover hidden prizes and unlock new levels!
We'll take a closer look at Cut the Rope in the next few days, but in the mean time you can download the trial and the full price version from the Windows Store.
