Thanks for the play and the feedback, I had fun watching the stream replay just now!
I can see a few people had trouble with the mouse sensitivity so that's something I have to look into. Watching the stream made me remember that people don't always play the game as I imagined they would - because of the mouse sensitivity issue you were playing very "conservatively" because it was so difficult to not miss the shots. (When testing, I didn't have that issue so was hitting extreme curve balls all the time and balanced the difficulty on that basis). So seeing that is a great reminder/lesson for me - thanks.
I was going for the over-the-top aesthetic (to make up for my soporific trading game last month) but the voice effect was not mine :) freesound.org.
