I've incorporated most of those suggestions into the latest release. Enjoy!

Cool! Thanks for the heads up. Believe it or not I've been continuing to (s l o w l y) draw artwork for the game. It's slow going since everything is hand drawn but I'm thinking about how much I want to get done before an "alpha" release. Right now I have 4 opponents with just 1-2 poses each, fully voiced with placeholder files but I'm still trying to refine the perfect AI generated voice for each character before I'll be happy sharing.
Still playing the game fairly often by the way :) Thanks again for making this in the first place!
I was using Google's Text-To-Speech API for the voices so far, but if I was starting from scratch I would almost certainly go with one of those voice transforming filters that are popping up all over the place. It's a lot more flexible and able to get the right intonation than trying to add SSML tags into text.
This one seems ok. Defnitely fun to play with. Though I'm sure there are better ones out there: https://koe.ai/recast/
