You've got a nice adventure game here with an interesting story and characters.
As a developer myself, I know it can be hard to judge if something is too easy since we have so much experience playing our own games. And I've to tell you this game was extremely difficult. I'd suggest having less mobs in the beginning and get the player slowly acclimated to the combat.
BTW the combat was cool. I didn't get far enough to see if the character gets more things to use in combat.
I'd also suggest adding customizable key binds.
The dialogue was a bit excessive for me, some voice acting would be a nice addition.
