This is a very basic gacha.
👍 Pros:
The graphics are ok and the game runs really smooth even on low end devices.
The rates don't seem too bad and you get quite a lot of summons at the start. The ability to save your pull during the free multi pull is nice.
The battle system is based around cards and interesting enough but you will probably be using auto most of the time anyway.
👎 Cons:
It plays out like an idle game. Already before the end of chapter two I'm stuck with reaching a roadblock in the tower for resources and not being able to continue in the story which means all there is to do is log off or grind stages. You will reach this stage within an hour meaning you've got less than an hour's gameplay before you're stuck and unable to progress.
There's no guild system and no friend system, not even chat unless I missed it.
So far the only gameplay is the story mode, endless tower mode and arena, all of them gated in some way. The story ends at chapter two and the tower only goes to floor 30 because it's apparently a beta.
There are different character traits like tank, damage dealer etc but there's no position setup which means in a group they are meaningless. Even if you have a tank most of the time the enemy will just ignore it and attack the squishy damage dealers anyway. It's really just means tank die last damage dealer and support die first.
It lacks some QOL like skipping battles.
The PvP is garbage. It insists on matching you we people higher than you so they always go first and whoever goes first always wins. On top of that from the time to matching you to the time you can just quit because you know you've already lost, is about 30 seconds making the whole thing tedious.
The game feels like a MVP that's in need of a large update. There just isn't enough in the game to keep anyone amused for more than an hour tops.
