When you make a shop system you put something useful in it not cloths.Instead you could have added a shop system with weapons and knives for close range.
It is so stupid that you have to wait 10 minutes for just 1 energy cant you make it like 5 minutes for 1 energy because i can only play thirty minutes a day because of this.And why does reviving cost so much it should not be doubling up the price to revive every time you die instead just increase the price of reviving by 2 every time.And for starters it should be 2 energy for revival every time they die and keep that price until they have all 1 star gear or higher.
