The phone version isn't a very good way to get the hang of it. It's still being worked on and there's a lot of features missing. The actual game has more enemies, crafting, more survival aspects, more blocks, different kinds of terrain/areas, NPCs, a levelling system and some other stuff. I'd recommend everybody to give the trial a go when it comes out at least, it's something you need to try. Notch (The guy who made it) has openly said he doesn't care if people pirate the game on PC so if wanna give it a shot theirs always that option.
