you need control
i expect you to have already played other webpuzzles, completed or not.
As you need to know specific things from other webpuzzles.
If you have not OR just dont wanna, the basics are: you will need to solve these puzzles, typically using the image name, title, source code and so on, after finding the answer, you will have to change the url name. For example: /startingpoint/first becomes /startingpoint/second.
you can treat these first 10 levels as a tutorial, after that. You will go to the REAL levels.
You have learnt everything you need to know now, Good Luck.
