No need to press the green flag...there are no scripts! Or are there? You need to complete a quest INSIDE the project. I don't recommend getting rid of all the comments, most of them are clues which you need to complete the quest! But beware! There are fakes, diversions and traps all over, make sure you are on the right path! When you have the password, type it in the comments.
Update - Made it MUCH harder >:) The password is NOT 2440. That is just a little...erm...thing that you will need to progress with the quest. The final answer is much harder to get than that! Original idea, I am proud of it :) When you found the password, type it exactly in the comments. You will know if you have done it right...so far, no-one has got it yet!
