I did a run in Horizon Heights on the 1st demo version of Sonic ATS and I wanna know if this counts as the final version since the layout of the 1st act barely changed except the shield change all the way to the left(which I didn't use):

I suppose I asked for this by not nipping that in the bud...

I'm going to say no, all runs should be done on V1.1. I'll put this in the rules.
