Anyway, not the best "guilty pleasure" type of game, in fact it was maybe one of the worst. The only strong point of this is waifu collection, everything else was done with minimum effort. Strategic aspect? Nah, just use whatever hero that slap the hardest (aka, rarest) since most the time skills just revolve around dealing %dmg+debuff. Graphics? Subpar with poor performance. Gacha? Horrid.
You're welcome to kill some time off w this game, but I don't recommend spending money on this as I rarely do so for any game from EYOU. For waifu whaling, seeks better built games like Destiny Child or Idle Angels.
