well from youtube gameplay it looks awesome.
i can confirm it is not in the ph appstore, only on android so far.
i am only worried about the money aspect, since HSWorld is much more money hungry than Evolution.
And in general, studios that were publishing almost fair F2P from Ubi and WarnerBros to PikPok, are releasing ever more aggressive F2P models. Take MKX with its doable challenges to obtain new characters, vs Injustice2 and Shadow of War, good luck getting new characters 1 fragment at a time.
I hope Hungry dragon will -at least- keep at the HSWorld levels. But as a realist, i dont see it.
