This is a sleeper isekai, in my opinion! Starting off, I want to comment on the overall quality of the craftsmanship. To be honest, it's pretty mediocre. The animation, while clean, was pretty rough. The CGI also wasn't that great. The visuals and art, though, were pretty good. I really like how cute and beautiful the art style is. The monsters look kinda goofy too!

Story-wise, the pacing is SUPER FAST! If you don't vibe with time skips, I don't recommend this series to you. But with that said, the pacing isn't actually bad. In fact, I like it. It skips a lot of unimportant details and mainly focuses on Allen's growth. In my opinion, with the way the story is structured, this pacing feels "normal." If the pacing were slower, we wouldn't have reached this point in just 12 episodes, LOL! Kidding aside, the pacing is fast, but it's handled pretty well.

Moving on, the story is very, very interesting. I really like the writing, and it's honestly super engaging. I also love Allen's random gaming references. They're just so fun! Though, there are a few plot points that I have nitpicks about, but they're nothing major.

Overall, I'd rate this series an 8/10. It's really great and unlike the usual isekai slop.
