The reason why you have to double click the flag is because of the bomb would show up on the first level but it does not start doing its scripts on the 6th level. So far, there are 6 levels in the platformer. You may have came from my comment in the Welcoming Committee. Thanks for paying attention for it.
To be honest, I don't copy any scripts or artwork. The only thing that I copy is sounds. But you can copy my scripts. No worries
