Fun enough, But too easy to hit the Pay wall. Grind and wait not worth the time.
The collection is hard to navigate without filters other than by element. Even when the game notifies you a girl or set is ready to level up, it shows all the girls, including the locked sets, and you have to scroll down each time to edit them.
Remember the game is free.

-This game no mate how hard you try the pay wall i there and over come everything
-Dead brain whale or dev bot with over power and block you out for all the normal combat or level up system that benefit there pay wall
-pass cost you 50$ and last for 10 day to finish the pass and you must done the mission to level it up( some mission is so ridiculous that no way you can get it done the only way to get it done is pay for is or you stuck
like example : mission will ask you level up 3 myth girl and guess what there no way you can get card you to level up it and then some *** deal pop up and say pay me to pass it )
-Gold is so *** hard to get too and *** expenses to use it for upgrade and only way to get it is 3 daily mission or pvp chest and event you got those each chest randomly give you form 50 to 100 gold and it got time count down to open it
-crystal there no other way to get by level up or pay for it and yes level up need lever your girl ( need gold to up them cost 50 to 200 gold for 1 to 4 but will cost 1k and more for high level and up max out is 25 you do the math each level x5) and it give you 50 crystal for each level
-gatcha is more joke 1500 gold for a normal roll that never give you mythic , 500 crystal for a premium roll that 100% give you 1 mythic , and 2000 crystal for a dam 1 mythic and some useless yin yang that you never use
and a *** loop animation is just dead no story no cgi nothing just AI image loop animation

Gameplay bursts are a little too short for a no-pay game though.
