Might not be for you.
A free trial might be better, given it’s hard enough you can’t past the first chapter.
Controls can be laggy and hard to get used to.
Boss fight, you can hardly see where you are on the mobile device, especially when your thumbs are covering sections of the screen.
Add a difficulty adjustment, drop the shop prices or make more resources available.
This game is not for casual players, that’s for sure.
