Story 8/10
While the story is kind of sketchy on the start )read- how the hell can they do that), it develops really nicely in the end. The scientists that they show us are very inspiring people and every time they introduce a new one, they show an experiment or two that they're holding at that time.
Art 8/10
The art is a good mix of 2D and 3D, as is usual. The characters are very moe (probably due to the age of the target audience) which limits their face details. The dresses and uniforms that they use are very detailed and accurate for the times which is nice as well. The animation is fluid, especially around the time travel parts. Also, damn all the male characters are p hot as well.
Sound 7/10
The voice actors did a good job, but that's all I can say. There isn't really anything to set it apart from everything else. The music (apart from the OP and ED) is rarely used which I find disappointing considering they go in past where they could use classic-style music.
Characters 8/10
The characters are well defined and in the end, none of the characters are perfect which I like. The scientists are my favourites in here because of how they interact with the MC's and they basically accidentally help them solve major life crises (and the opposite happens are well). As for the main antagonist, he isn't all that "black" as you would think and I appreciate what they did about his "demise" in the end.
Enjoyment 10/10
Being an electro-technics student, I very much enjoyed watching this anime. I actually learned a few things from it as well (namely how a morse machine works :P). The characters are good and the story kept me going until the very end. Since I am also a fan of isekai-esque shows, this was right up my alley.
