Even with your fg, you should be fine starting out as barb.
Buy low/mid clubs, str/ee armors, str charms of mp for low fg amounts. Then invest ~ 200fg on 100+ ee mq club, ~150fg on mq 100+ee heavy armor, and ~50fg on str mq charm.

I do play from cellphone only, maybe not perfect, need to be careful sometimes with clicking/dragging things. But it is definitely playable.
