I want Saitama's level strength. I want to one hit everybody instead of running around like a timid, weak ghost. I don't even know whether I am dealing damage. I don't like to be weak. Make the ghost strong.
Others said the ghost is strong while you say it is weak. I would suggest you start looking for every bullets and see which one you like the most.
You're meant to fight them with the limited space. There's a patch coming soon to block the area with doors for the true combat.
