Aside from a handful of quality of life changes like the wheel automatically spinning to the next rune if it runs out, the ability to spin the wheel backwards, the projectile deflecting attack deflecting non boss objects like the crabs in fight two, and the blue shot being a lot faster, among other things, I really like what you've got here. I love runes in general so this setup really spoke to me, the capacity synchronicity in this system was really fun to play with as I did run after run, and due to the progression system, a lost run never feels like a waste of time which I really appreciated! I also found the bosses to be really cool in terms of animation and dynamism, fantastic work getting those done
