This isn't that bad - if you could just cut out the harem part. It just brings to mind the Oglaf dimorphism comic - all demihuman women must look significantly more human than the men, for some reason.
The MC is a bit too OP - it would feel better if he outsmarted his opponent occasionally instead of steamrolling them - and every character is behaving very exaggeratedly.
Overall, I give it 6.5/10, rounded up to 7 because it has a certain charm.
To raise the score, though, I would need the author to fix their biggest flaw and actually start planning the plot more than one chapter at a time. Every chapter it's just like "oh, by the way, let's talk about the fact that golems exist", and then a golem shows up that chapter. Integrate your plot into your worldbuilding to begin with, dude.
It's like every chapter, the author is unpleasantly surprised that the manga hasn't been canceled yet, and then they have to come up with the plot in a hurry...
