A fantastic game that incorporates the series extremely well

As a big fan of the series I love that you have made a game as fitting as this one that incorporates both the adventure and the town development of Rimuru’s story. I especially loved the fact Great Sage can be interacted with to help you find out what to do next or review things you might have forgotten in the tutorials.
The game original story is nicely added in where it does not disturb the canon of the main story and adds interesting new characters and concepts that I thought was fairly fitting to the world of Rimuru’s.
One thing that I wish was easier in the game is the world building section. It’s rather painstakingly long to organize all your buildings into a nice looking town especially after getting your central office and property upgraded. I hope they’ll add some features to make it easier in the future. For now I’m probably going to just focus on the farming and wait for such an update to make my town look nice.
Besides this and some very small features that I’m sure will be taken care of at some point (like getting stuck in a battle), the game easily turned out to become one of my favorites regarding. I’m heavily impressed and this game is only 3 months along! Plenty of room to grow and I look forward with extreme eagerness to see it.

Pretty great game

I don’t usually play these types of games but I loved the manga adaptation and anime adaptation and decided to download it. First off your given a lot of stamina from quests and you could play anytime without having to wait. Second, the Secret Skill animations are pretty cool as well as the skill animations. Third, I like how it’s not just the Orginal Story but also some events. Fourth, it has a lot of ways to increase the power of a character like leveling up character, awekening character (or increase the stars), forging weapons, leveling up weapons, evolving weapons, leveling up skills, evolving skills, unlocking health, attack power, defense, and input through ability release, and talking and bonding with the character in your town or interact menu. Fifth, you can build your own town, although you can’t really change the shape of land (only by leveling up the town centre) or add pathways, you can still add building to give you resources and build decorations, think of it like Clash of Clans or Boom Beach without the towers and units. I think overall it’s a great game and although right now it has some bugs and features and characters yet to be added, it’s fun to play a few battles every now and then.


Not too hard not too easy

First this games draw rates are amazing I love to play gotchas but I'm usually ftp like with this game. I haven't spent a single dime yet and have summoned quite a few times and have gotten pretty good characters out of it and that has allowed me to play with and build characters I actually like from the anime.

Second this games balancing is perfect, as with most gotchas you draw a high tier character and you can dominate the whole game with ease but this game makes it so that the characters being used all have to be leveled and equipped no matter the rarity. There are of course some characters who gain a advantage simply by being a higher rarity but its not such a big advantage that other characters are out of the picture completely.

Third I would like to thank the developers for taking careful consideration into the game when making events and leveling rewards because the events and rewards have helped me out tremendously throughout the game and I wouldn’t have advanced as fast as I have without them.
