Thanks for playing and the feedback!! Nice to hear you liked the fate animations, I spent wayyy too long on them lol. You're absolutely right about Medusa, that whole fight is super scuffed, I didn't really spend anytime balancing that fight and just wanted to get it in the game before the deadline xD. And you're the second person with the end cutscene issue, I definitely should have disabled restarting there.
As far as the theme, it is definitely a bit of an abstract interpretation. I used the definition of spin as "to draw out and twist fiber into yarn or thread" in the fate cutscenes with the main character, and the definition of "to plunge helplessly and out of control" as the lore of Dante falling through the circles of hell. But I can see that being a bit of a reach hahah. The main character's spin attack and the confused star animation on enemies were the more concrete theme applications.
