Did you test this yourself?
Quite unplayable... there are loads of coins that are just above head height meaning you have to jump to get each and everyone of them, this becomes a real pain where they're all a long line. The overall feel of controll seems a bit laggy and you've set it up so sonic can jump waaaay too far. I also died randomly jumping back up a platform, no spikes, no baddies... nothing there, but I died anyway. I stopped playing after this.
I think for what it is, and considering it's been done to death this is not an impressive attempt. You should have play-tested it to death and fixed any issues that arose, there's some fierce competition when it comes to "good" sonic re-incarnations... so why submit something that really needs more work?
All in all, a nice crack... and it was enjoyable for a short while, but there's so much better out there in this category.
