A little ship spawns on your webpage. It can shoot bullets. When the bullets hit an object, the object disappears, and you earn points (the amount is based on the type and the size of the object.) Once in a while, you will get some text on top of your screen, saying “bomb is ready 3.. 2.. 1…” the bomb destroys stuff and helps you with the game. Technically, the whole purpose of the game is to score as many points as possible. Have fun!
Once bookmark was pressed, the hack will not activate yet. You will see a little red shield with a red cross on it. It’s located all the way to the right of the URL bar, near where that bookmark star is. If you click on it, it will say, “This page is trying to load scripts from unauthenticated sources”. It’s perfectly okay and no viruses will be downloaded. Click “Load Unsafe Scripts”, and the page will reload. Then, you click the bookmark hack one more time and it will work! Again, this is perfectly safe, and the reason google is warning you because there is no way they know what javascript you are inserting into the page due to the reason that the javascript has a link in it and they are unable to see it. Google’s just getting suspicious. Screw the warnings and get on with the game.
