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.
