As someone who has played thousands of games of Shattered with >600 games just on my most recent phone (108 of those ascended) and has ascended with all the sub-classes... git gu... no, no, no, ask questions. Some of the mechanics are kind of subtle and exploiting them can take thought. I personally find the Huntress/Warden the easiest (because the spirit bow has unlimited ammo letting you sell off thrown weapons and the free seeds and dew drops can keep you alive).
I just read the specs and there is an SD slot.
