Played through the demo. Gonna echo the others-feels real short.
But the artwork is great!
Now, critiques:
1) Gallery doesn't have an exit option. Can't hit Escape or something to exit it early.
2) WASD would be a lot better than Right Click for movement. Especially since Right Click is also camera.
3) Sometimes the Attack selection didn't work right-I couldn't target a mob right next to me.
I will absolutely be following this, though!
