Today at the Google IO was release the first beta version of Angry Birds for Chrome you can download here Angry Birds for Chrome beta

A few hours later (like 3 hours) was “hacked” you can found full articles here:
Developer page (Wes Bos)
Site where I read the article for the first time (The next web)

I try the hack refered on the last site and found a big issue after you try the reverse code the game is “locked” after review the code I found the issue let me share my findings:

First level is locked so you need copy and paste the code below on the browser and you should be able to play without issues

javascript: var i = 0; while (i<=0) { localStorage.setItem('level_star_'+i,'0'); i++; } window.location.reload();

but after check on the develop´s site (@Wesbos) he even solve more efficient the issue but I think that can help you to figure it out how works and make some other variations like unlock all the leves without any stars

javascript: var i = 0; while (i<=69) { localStorage.setItem('level_star_'+i,'0'); i++; } window.location.reload();
