Fun but be prepared to pay
P2W And Boring
Also there is no way to recycle materials you spent on equipments, and it takes so much time for you to grind to earn enough upgrade materials (Of course, it has a stamina too). Similar games like Archero have a recycle feature and it's a popular game compared to this game which has a pretty small population.
It's not enjoyable unless you're willing to spend at least $1000~1500 every month. So if you're new to this game, just play for fun without buying in-app purchases. Becuz in few hours, you'll hard stuck at some point and feel extremely bored grinding same map over n over.
