Thank you very much for taking the time to play and stream the game. Yes, the name of the game is a reference to the fairy tale Rapunzel, because your hair grows longer the more points you get.

I think you often attacked a little bit too late, but maybe I also was a little bit too precise with my colliders (as soon as your body hits the tip of the sword, you are already dead). I probably should've shrunken them a little bit down for a better gameplay feel. So I take at least half of the blame here.
Regarding
> Everything kind of blurs into the background and it's tough to see enemies and projectiles
I absolutely agree with you here, especially thanks to the stream, I saw how much everything blended. I also noticed this during some of my playtests, but I think I was not ready to kill my darling (i. e. keeping those colours and refraining from the use of outlines). The general look appealed too much to me to change that, but from a gameplay perspective that's absolutely problematic.
Again, thank you very much for your feedback! :)
