This seems to be really really early. A lot of the Animations, like strafing, Jumping etc. are missing, as are basically all Abilities, except for the one berserk ability.
Combat seems to be working, but I can move freely during all the attacks, might be better if they lock you in place a bit, but I think its too early to tell what you're going for, if its supposed to be a more slowly paced RPG or a more action one, I could see it going both ways.
Music is nice, I can see some Ambient getting there, but currently its obviously a bit empty.
Interface looks good, but I couldn't get back out of the class glossar to the previous screen of that interface once I clicked on a class, having to cycle through the classes with the small arrow buttons instead.
Key bindings on T, U and Y seem odd, dualwielding doesn't seem to be implemented despite Barbarian having skills for it, as I could only click on a weapon to equip it automatically to the mainhand, not drag and drop it into my desired slot.
I liked the little chest on the back opening up when accessing the Inventory.
I really didn't like that the camera is default unlocked, I would prefer if it was just locked to mouse movement unless you're in any kind of menu, so I don't have to constantly hold RMB down while playing.
when rotating the camera not the character via MMB, moving forward moves in characters facing direction, not in camera direction, feels odd.
I could see this going a long way if you get all the classes and combinations implemented properly.
