I answered the form, it's a good proof of concept! Just wanted to point out that I died against Pippi when she sent me into the brambles with the "wind", the screen turned black... and never faded back in. I could hear her throwing attacks then, but I'm not even sure she was hitting me?
Also a minor thing but pausing during the boss fights doesn't stop the boss music, so you hear both tracks at the same time.
Anyway, hope to see more of this in the future, keep it up! :)
