I'm trying to go through it again. After 3 bosses, I'm 11 minutes in. So hopefully, if I can do it right, I can beat it under an hour. 90 minutes at least. Galaxy Man's stage took 4 minutes just because Galaxy Man sucks with the Mega Buster time wise. My goal for 8 bosses is 25 minutes. That might be too good for my skills, sadly.
