Very bad judging/sync, but good overall
I understand how RIDICULOUSLY DIFFICULT it is to get flash to do anything with good timing. I've tried myself. So for that I forgive you. However, there were some serious issues with the judging. I can handle off-timed arrows, but just lining them up with the action zone didn't work either, arrows that were clearly perfect must have dropped frames and gotten misses.
The heavy song, if it were official, I wouldn't give it more then 7 or 8 feet. It's VERY easy to do on the keyboard, on Stepmania I would AAA, or possibly AA with a couple greats.
So..... some real bugs u gotta work on there, but apart from that, not bad.
