Legend of Sihara

sorry but i dont get the controls.
doesnt seem like there is no sword for use at the beginning availlable so it must be collected.
however explored it as fars as possible without fighting abilites.
only collect the bag from that first chest but no idea what it got me.
anyways I'm now stuck there.
at leat it got me 5 exp even though that ain't helping me in any way :-/


Edit: Oh wait that shadow at the beginning was actually he entrance to a house! :O
looked too much like background for me to recognize it :-D
