I have another point to make about this level, In the original Green Hill when you run up the hill near the beginning, take the spring, land on the top of the mountain type thing, you jump down onto a bridge like structure, it collapses in two places as seperate objects when you run across them.
In your version, you jump down, and for some reason you have the bridge to the right, because of that I just ignored it and jumped over the pit to the other side, which is wrong, the bridge should be wide, and in the centre, so I'm forced to take it when I want to go to the other side, because your bridge was on the right, I ignored it because it would take too long to run to the right, and then take the bridge compared to just jumping over the pit.
If you're not sure which section I'm on about I'll get a pic later, I can't right now.
