It's just the same thing but a web upload instead so it may have more bugs for all I know (though I do hope against that)!
If this is illegal for the jam (or smth of that sort) then do refrain from using it.
You will have to rate at this link though instead since it's the actual submission:

Any and all feedback for improvement would be valued!
