I want to make a level selection menu. I know how to make them but my question is, is it possible so that if the player has not reached level 3, he cant click on the level 3 icon? I would also want to know how to make that be saved on the game file so that if the player comes back, he can select the one he stayed in.
I am planning to publish my game in HTML5 so the game has to be capable of saving that info on a cookie or something.
