Ya know...
you put some good thought in to this apparently, but the error with no progression after knuckles and the chaos emerald kills it all. I WANT TO SEE THE REST! IT LOOKED LIKE IT WAS GETTING GOOD! please resubmit after you fix that, and also don't make clicking/space button-pressing mandatory for video progression. sometimes, the viewer just wants to sit back and watch without having to press anything. Trust me, fix those problems and it will be much better!
