Fun game

I like the way the game is played sort of a open rpg that you can counter and block enemy attacks and even escape them. You can equip items and improve stats through a grid. I think it’s worth the time to pay if you are into that.

Needs to be fixed

I would have put five stars but there a bug fix update...
That I can't get cause it not saying it need to be updated on the app store but on the game it tells me to update and won't let me play otherwise and I'm most def not going to lose my stuff because I can't get a big fix update i don't wanna reset


It’s a really good and amazing game, I’ve gotten really far into it and am a leader of a strong guild. I would recommend to watch SAO the anime (in Japanese dub) to actually understand 5e game better.
