Not bad, bro. I really like the concept and bgm. Suggestions...
-the 1.1 def file is missing some crucial parameters that are essential to 1.1. Things like tension high, tension low and overdraw.
-There are some typos in the 1.1 version. There is a decimal instead of a comma in the cloud bg code.
-I'd lower the whole stage and ditch the bound low value.
-If you want to keep the fighters on the sidewalk, that's cool but you should use the road for something. Maybe have cars passing in front of the fighters.
There are other little things, but it's probably more preference than necessity. Keep it up man!
