Visually, the game is incredible! And the combat mechanics are very interesting. But it was a little too difficult for me. I couldn't concentrate on the wheel, on moving my character to avoid the boss and all the projectiles, and on getting the cursor to turn around my character. I also found it very punishing, when you get hurt, to have to cancel skills that you have to charge before using.
But I think that by reducing the number of projectiles, the game would already be much more balanced.
In short, a great game that doesn't need much to be a delight to play :D
