Honestly my recommendation on bosses that allow it is Charge & Chaser/Spread since you have an option for if they get stunned/don't move much and to just keep a small but steady amount of damage if you have to move a lot
Spread for the little tiny people and other close range stuff since its DPS in the original game is ALMOST as good as perfectly times Charged Charged shots
Yea no I think for Obama you wanna switch from Chaser when he's up to Spread when he's down since you get the hands while he's up and can hit hard while he's down. Or roundabout for the big knock-out damage
I’m sorry, you called boss obama the hardest boss to fight at 8:37? Ican literally get SSS as Engineer, Neptune, Homer, Kragg, Blacksmith, Dry Bones, what ever character is available, not to forget, I don’t use cheating stages and cheating buddies, how about you just pratice dodging and parrying him, that can work since I fighted him a bunch off time.
