Not impressed. Been playing for a while now. Main issue is World energy. Yes you can play for free..sorta.. But not for long. Defo not long enuf to grind it. Very money orientated. Devs should take note. Yes you should be paid for your work absolutely. But this style of gameplay very outdated now. OPTIONAL ads you can access anytime to increase stats is the way to go guys. Not worth spending anything on right now, sorry uninstalled.
