This game is much better than I expected

Honestly, I thought this game wouldn’t really be all that but it’s actually pretty good. The gameplay is nice and smooth, of course the character designs are good and it’s just fun to play overall. I can see myself actually continuing to play this game for a long time. My only problem though is that there are way too many micro-transactions. Even by gacha game standards, there’s a lot. On the other hand, the developers are very generous as the free rewards are quite good which is not exactly the most common in some of the big name gacha games. Either way, great game and I swear I will get Asmodeus when she comes back.

The game itself is good but it have a fair share of problem

First let me get thing straight, this game is great, it have everything I like and expect from a typical gacha game and the free rewards and events are not that bad.

So let get straight into the problem why I give this game a 2 stars rating( note: I will update this review depending on dev’s response). This game have some serious loading issues, I don’t know if it only a problem on IOS because every time I play this game on my PC it work fine but a moment I tried to play it on my phone, the game just doesn’t want to log in and I have to close the app and open it again multiple times just to log in. It also have huge problems when it comes to in-app purchase, every time I buy some pack, it took the game 8-10 hours to process my order and sometimes it took a whole day. The game itself is fine but if those issues are not getting fixed, this rating will remain the same.

Bad faith Dev response *UPDATE*

After posting about the constant issues with the game loading, the Devs responded that the issue was not on their side and that maybe it was an issue on mine. The loading issue does not occur at all on any of the other 3 mobile games I’m currently playing. I feel that eliminates any questions they had about Wi-Fi or my “telecommunications provider” being at fault, which the devs would’ve known had they asked me a single question about the issue and not rushed to blame me for the problem. They also stated that any similar experiences were not being reported by other players. A quick look through the recent reviews definitely reflect that this issue is more widespread than they’re letting on. I haven’t been able to login at all today, and if I can’t get it to work, I’ll just uninstall. The game is cute, but not worth the headache and bad customer service.
