The gameplay is simple and dynamic. The only bad point is the inability to fully control your characters. Being able to do so would probably make the game too easy though.
Multiplayer is quite good since people can't get kicked out after they join. It doesn't matter if they fck up the run since there is no stamina.
The story is also great for a mobile game, the trailer was top quality and the OC Sufika is interesting enough. Though it won't really make sense if chimera ants are added to the game since this game is supposed to take place between GI and CA arcs. But let's wait and see :)
It may not be the extremely awesome HxH game we all want but it's still quite good for mobile and the story is already better than other gacha games. Plus it's incredibly f2p friendly!
