Thanks for your bug report.
I tried to replicate your issue but the game didn't freeze in any dialogue, once the jam voting phase is over I'll try to fix that.
it froze at the start of the new wave, I lost the first wave by timing out and then skipped all the dialog by clicking as fast as i could while loading up a second, and then it froze at the countdown at the start, hope this helps!
Okay, thanks again! :D
I'll play the game just as you described, and then hopefully fix this issue!
