While a bit confusing at first, I ended up liking the game a lot more by the time I was done with it. I had some trouble understanding how the spell system worked (I think I figured out that you actually combine spells by selecting a slot to put the newly-dropped effect in?), and my final run eventually ended when both me and the boss spawned inside the walls of the level, but in the meantime I had fun overcoming basically any number of heads with a legendary spread-shot/trained asteroid/common strengthen combo :-D
