Meh. I give it 6/10.
The MC feels very passive; often, the only reason he does stuff is because a God personally tells him it's a good idea.
This manga features the very laziest form of Isekai; memory loss just enough that he can tell that he's from another world, but not enough to actually have a personality.
Did he do anything to deserve his awesome powers? Not as far as anyone can tell; it just happened.
My take is that the author did zero planning and is just flying by the seat of his pants.
Giving the MC a backstory would take work, so he didn't do it.
