Since there aren't any reviews as of writing this. I'll be the first then.

TL;DR, it was a good read. I liked it.

Story: 6/10
It doesn't feel like the author has much of story to tell. It just feels like author wishes to put his characters into funny situation. But I feel like there's potential for future developments so I'm keeping this on "Reading" for now.

Art: 7/10
I've seen Hentai artists with better art than this. But it's not bad.

Character: 6/10
Way too early to have any sort of character development but they're funny though. Gets a decent score from me.

Enjoyment: 8/10
Comedy that gets me to laugh is always enjoyable. The "Tsukkomis" and face reactions were what got me laughing.

If you're someone who enjoys "Tsukkomi" comedy, then this may be a good read for you. The whole point of this manga is what if our main character (MC) goes on an adventure like in Pokemon but instead of catching em all, he's gotta impregnate em all them girls because his entire motivation is to get a harem. It's right there in the title. Even it may feel like a wish fulfillment, and it probably is, what made this enjoyable for me was the absurdity of the situations the MC gets himself into and the reactions to these crazy situations. It was a funny read and I had a great time reading.

If there is a problem with this manga that I wish to point out, it is the "Isekai" part of the story. The MC reincarnated into a fantasy world in this manga. I'm not saying it a problem because I think "Isekais" are low cultured wish fulfillments, I say this because it's a useless plot device. If the author were to make the MC a fantasy world character rather than someone who "Isekaied" into one, it wouldn't have the story any different or any less enjoyable. It did nothing to explain the MC's personality and motivations. In fact, the only time so far the "Isekai" part was utilize was when MC decided to cook a recipe from Japan with Japanese flavours that can't be found anywhere in this other world. But in this "Isekai" world, its residents know of and serve "Dango", WTF author?, you made a plot hole.

Overall, it was a good read. If the "Isekai" part was better utilized, it may have gotten a better score from me
