Cut fruit game based on HTML5 and JS

Cut fruit game used to be a popular mobile phone casual game, today to introduce is a web version of the cut Fruit game, by Javasript and HTML5 realize, although the difference between the function and the original is too big, but the basic function or have, or imitation of quite lifelike, Have a certain level of javasript friends, you can look at the source code, I believe your javasript level will be a great upgrade.
