Not bad but....
The reviews on newgrounds are going to probally be from younger kids.Im thirty four so Im starting to feel you.I believe that this would be better if you added a choice of a few music pieces to choose from with the option to switch back and forth from. Then at the end add a button so you go back to the beginning of the submission so it doesnt merge together with the audio from the last page and the first page playing at the same time. All in all I would say that this is a pretty good "controlled rant'
