Sonic 2006 White Acropolis (Sonic) 1:33:638 Speedrun
Been a minute. But I just saw a run using this technique and I thought it looked simple enough, so I pulled it off. It wasn't too hard, probably spend around an hour getting my time down to what is in this video.
Pretty casual run, but it was still fun. Also, first 06 run so- I guess that counts for something.
