This is very good! There's a lot to like about this game and the developer's love for it shines through every step of the way. For me, the exceptional features are: the super well-made character models, the lewd scenes (the majority of them are put together with great care and choreography, as well as some pretty hot dialogue), and this very wholesome and heartwarming relationship progression with the girls and how we become more and more intimate as we interact and learn more about them.
I am also enjoying the story and the world building quite a bit! Both the high-stakes and the slice-of-life moments are enjoyable, though I do think this game is at its best when it's not taking itself too seriously. The references and meme-y moments are hilarious, with my favorite ones being the unhinged scenes with multiple characters onscreen being chaotic as hell. Oh, I also like the MC. He has a good balance of being a good, decent guy who is trying his absolute best for his loved ones while also being a very relatable level of pervy, as well as equal amounts badass and stupid!
If I had to nitpick something about the game it would probably be the translation because it can be somewhat broken at times (mi lengua madre es el español y me es fácil ver cuando el diálogo corresponde a algo en español que no se traduce 1:1, como cuando Charlotte le dice "What a rare human" al MC). One last thing: I also think the lewd scenes would be some of the absolute BEST in the genre if they had at least partial voice acting. That would seriously take them to the next level!
Absolutely give this a try if you like harem VNs with an isekai element, lots of hot girls and scenes, and a nice, slow-burn story that might tug at your heartstrings if you let it sneak up on you! To say I am really looking forward to future updates would be the understatement of the year!!
