Pharaoh Man is the worst. His first phase takes a long time to learn, and it can still frequently lead to situations that are impossible to dodge. His second phase is even worse. The Sunstar he summons will deal unavoidable damage every few seconds while on screen and takes 6 damage to kill. It's technically possible to avoid getting hurt this way by firing a fully charged blast as soon as it appears, then quickly landing 3 more shots. In this fight I take 3 ticks of damage from this bullshit attack. So maybe it's not exactly a perfect run, but it's the closest I'm willing to do.
The stage itself is easy, but Doc Enker is about 50/50 for getting by unscathed.
Thanks for watching. As for the rest of the game, I may continue, but it won't necessarily be no damage nor buster only.
