Oh, man is it hard and you can group and compete against console & PC Gamers.
I never could get used to iOS controls for first/third person games like Minecraft and shooters. Far too slow and clunky.
I am amazed how true to the console and PC version the game is, it's the exact same game, same world, same servers, just different controls. If you use a controller with your iPhone it would play exactly like a console.
I have 3 invite codes available if you have a newer iPhone (works best on iPhone X) and want to try it out.
