Slime: Isekai Memories, the review of the game from Slime Life

Also arriving is the Vita da Slime mobile video game, or Slime: Isekai Memories, which takes the form of a gacha RPG with management elements

The trend is now well established: anime series can be the perfect starting point for the construction of mobile RPGs with gacha elements and Japanese publishers never seem to have enough of them as well as evidently not even the public, otherwise they would not come out so many, as evidenced by this review of Slime: Isekai Memories. In this case we are talking about the adaptation of That Time I Got Reincarnated as a Slime, series created by Fuse and carried in animation by Yasuhito Kikuchi and Atsushi Nakayama with great success around the world. Bandai Namco has the rights for the video game adaptation and the rest is easily predictable, considering the structure of the manga/anime: another mobile RPG in which we have to collect allies through a draw system, compose a party and face increasingly threatening challenges in turn-based combat.

On the other hand, when an anime features a large and varied cast, complete with the inevitable “waifu” of various types, it seems practically made for the construction of a video game of this type.

We do not dismiss this game in a hasty way, however, since there are some peculiar elements that stand out even in the midst of the huge amount of similar games: the main feature of Slime: Isekai Memories is the fact of combining, to the classic structure of progressive turn-based fights, even a system of construction and management of a city that manages to vary significantly the structure of the game. It is difficult to find a really convincing cohesion between the various parts of this multi-faceted title, but for fans of the original series can be an engaging pastime, while for others it can be an excellent introduction to the story in question, so it certainly has elements of interest a bit ‘for everyone.

History of a slime

In Slime: Isekai Memories the story is told with scenes taken directly from the anime

The story of Slime: Isekai Memories is basically the archetype of the so-called “isekai” genre, which involves a protagonist suddenly transported to a world completely foreign to the one he is normally part of, starting fantastic adventures. Often this world takes on fantasy connotations, but it is not a strict rule: what represents the foundation of the subgenre in question, which is always a huge success among light novels, manga and anime, is the fact of presenting a character, usually humble and unimportant, in a context completely foreign to his normality but where he can redeem himself by taking part in an adventure with epic implications. In this case Satoru Mikami is a normal man who, after being stabbed for defending a colleague from a robbery, wakes up in a fantasy world embodied in a small slime. What is practically the most insignificant of monsters soon becomes a predestined for enormous feats when it is discovered that he possesses special abilities and can contain the enormous power of an ancient dragon, which sets off his incredible story.

The narrative has a role of fundamental importance in Slime: Isekai Memories, which in fact represents a sort of transposition of the anime in a partially interactive form. As for the “quest”, in fact, we are limited to scroll the story between screens and interlude scenes, following the original anime with some original grafts, written specifically for the video game by the authors, allowing in this way to insert some news for those who already know the story widely. Even these parts purely narrative denounce a bit ‘the problem of general cohesion of the game, since the quests are limited to presenting narrative moments and fights compartmentalized, with clear breaks between a section and the other.

Gameplay between fighting and construction

Unlike what often happens with games of this type, the interface is not extremely complex and overloaded with banners and buttons, resulting rather clear and divided into a few readable options, which is certainly positive. From the main screen you can access the various sections that make up the gameplay, or the missions, the construction of the “world” and the management of characters. The combat system is turn-based and is based on the association of equal icons in order to increase the effect of the attack through a multiplier, which increasing then allows you to unlock more powerful attacks. These moves are quite spectacular, merging 3D animations with sequences from the anime and creating an effect really convincing and nice to see, which dilutes if nothing else the tedium that these clashes tend to create in the phases of grinding, which can also be solved through time acceleration and auto-battle, with the obvious adverse effects in terms of game play, however.

Deeper and perhaps even more interesting is the management aspect, which takes the form of a sort of city builder: with this option we can devote ourselves to the construction of our city, which houses the various creatures and populations to which we give accommodation.

There are different structures to build with different functions, each requiring a certain amount of resources and time to complete (except through micro-transactions). The particularity of this mode is the fact that you can at any time “enter” the city in 3D to visit it and talk to the various characters, which has effects in the development of these and allows you to activate additional missions or get useful materials.


It is not easy to find something new to say for a title that follows rather slavishly the canon of the genre, including its well-established distortions. Slime: Isekai Memories has a combat system that’s uninspiring even if pleasant to look at, a progression of quests that merely tells the (good) story as a sort of visual novel, and the usual gacha traps. It does have at least one rather original element in the construction and management of the city, which can easily be the most interesting part of the entire title, but it’s hard to get past the feeling that the whole thing was put together without a truly cohesive and unified game idea. If nothing else, Life of Slime’s story still comes across as enjoyable and interesting, with a colorful and charismatic cast providing a drive to keep going.

  • The city builder management part is curious and interesting
  • Spectacular moments during the fights
  • Uninvolving combat system
  • Very little cohesion between the various gameplay components
  • The usual distortions of the free-to-play gacha
