It’s so unexpectedly addicting?

I was getting tired of another idle hero collecting RPG game, but gave a try to the game due to the water magician collab because I liked the anime, but who’d knew I’d be hooked with this game even after getting the character I want? The gameplay is so therapeutic and enjoyable, especially for busy people who don’t have time to sit and stare their phone 24/7. And most of the heroes design are very likeable, cute visuals and skin designs too! Last but not least you wouldn’t expect the community inside the ingame chat to be very welcoming and informative towards the newbies, answering even the silliest questions a newbie can throw to them. Great experience overall.
