Fine, except for 2 things: 23/3/20

Game often crashes randomly. Without reason. It could happen just after a battle or just navigating the menus. Still unstable after months since release. The second problem is the soft cap this game has when upgrading your Nikkes. You need to get the same SSR Nikke 3 times (the chance for one of them is 2-4% depending on which recruitment you use). And just when you got 3 of the same SSR Nikke, you need to get 4 different SSR Nikkes (and yes, 3 of the same for each of them) in total to get out of the soft cap of level 160. This is a serious problem as you can literally not progress through the game because all the enemies and stages will be too difficult. Without getting 3 of the same Nikkes 5 times, it’s impossible to enjoy the game more.
