I played through the game, I enjoyed it to a certain degree, and I think it'd work fine as an okay, if simple, linear visual novel. However, it's marketed as a "Choose Your Own Adventure" title. It's the top tag as of now, actually! The problem is... the choices don't hardly matter.
You get a bunch of options, yes, probably even "hundreds of decisions" as the store page says. But, many of those are poorly-disguised exposition that you can choose and it brings you back to that menu with that option exhausted, allowing you to just click them all regardless. It's less of a choice and more of a list of skip-able dialogue that could have simply NOT been a choice to make.
Still, the vast majority of choices to make give you options to roleplay. Great! You can be a classic milk-toast nice-guy, a lustful smug hedonist, or an apathetic voice of reason. That's... well, if you have the imagination and you really get into being the guy you're playing, then you can fill in the blanks and have some fun here and there. The options are pretty consistent, though my least favorite is the mandatory moment where you suggest Amelia, the underage mage, go seduce a guy and the game grills you for even THINKING that was an OPTION! (Even though you cannot proceed until you do so.) There's a few more times like this, but this one felt particularly railroad-y. Whatever, I can squint past it, I guess.
Continuing on, we come to the relationships; the game's most highly-praised and well-explored feature. Having said that, it actually is pretty good. The characters are fun, the dialogue itself is fitting, and I thoroughly enjoyed the comedic aspects of the story. I'd say this is the game's bread and butter. If you can look past the choices being a little underwhelming and the single romance option being very... generic, I'd say they did a nice job. Especially the VAs!
Finally, though, I'd like to gripe about one more thing: the endings. In a general sense, mind you, not necessarily the content itself. The problem I found with them was simply that the choices you make, through dialogue and interaction... mostly don't matter. Aside from the obvious difference in whether you romanced the blonde, Leanna, or not, it mostly comes down to this: Did you fail a bunch of quick-time events? Bad ending. Did you do good? Have a whirl at the ending-tron, you can purposely fail the battle (for some reason), you can win by doing the thing, and then you can either go home or stay in the fantasy world with your babe.
It really, honestly disheartened me when I realized that the only reason I got a decent ending was the literal side-attraction mini-games. The choices regarding anything but romance don't really matter, and (try as I might) you can't romance the female lead as anything BUT the classic milk-toast nice-guy. It super bummed me out since I got ending E, where you spend the rest of your life with hot, cold, steamy, elemental babes. Since I was going for the pervert archetype for the comedy, I pretty stoked before I replayed the game and realized how... hollow it was.
Basically, TL;DR, I feel like the store page built me up for a cool, multi-faceted, character sim where it was actually a very singular, linear story that also has some dead ends you can hit before you get the "intended" True End. If you like isekai a LOT and are hungry for more, I can recommend it for the comedy at least. Otherwise? Sorry, but I'd read something else.
