Very bare bones so can't really add much to what others have posted.

However I do like the concept of class mixing for adding variety.

Couldn't find any notable bugs in the time I messed with it.

It's a bit unclear how classes work though.

For example, why does the Warlock show no abilities for the primary class.

Are certain classes not meant to be primary?

Interesting concept regardless.

Very cool demo. I like the atmosphere so far.  I wish didn't have to press a mouse button in order to move the camera. I would prefer if it was locked and the mouse button can use your slot 1 ability or something. I was a little disappointed that the spells didn't do anything yet, but I understand that the game is still in its early stages. It seems as though adding classes allows for learning spells that are a combination of adjacent classes? If so, that will be a fun mechanic to play around with. 

When you level up, sometimes you are given the option to unlock one of three classes. But it seems you can only have 3 classes max at a time, so I am curious to know what else you get to pick from when leveling up once you set your 3 classes.

I look forward to playing once these mechanics are fleshed out.

idk if its because its missing them but warlock doesnt seem to have any icons for its skills in the class equip screen

also moving the camera with the middle mouse button will make it so the character doesnt move in relation to the camera, he will move in the direction hes facing

Great start to a single-player MMO style game. Unique and interesting progression mechanics and cross class character building, if done right in the coming days, could make this game one hell of an RPG. Attack and movement feel already point to this being the case.

I don't know if I quite dig the "misses in RT combat" approach, perhaps damage number ranges would suit the game better. 

In the visuals department the game looks great. The enemy designs are striking, the lighting is dark without being unseeable, the UI is excellent and the skill icons are vivid.

I give Orthello, Son of Death: I spent 6k hours in FFXIV so "MMO" is a compliment/10

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.
