Personally, I think this would be a good idea and it'd be in the spirit of the jam. So yeah, go ahead with this!
We just want people to make a simple game, you see. So we're hesitant about animations with many frames, etc.
ahh i see! i was referring to the usage of online TTS generators like this https://www.tetyys.com/SAPI4/ to generate lines not voiced by the voice actor !
If you're trying to use TTS to voice several characters, that would be a no. TTS is meant to be used for accessibility purposes and not to bypass the VA limit. We ask people as well to use the TTS in-engine if possible.
But I'd like to remind you that you can have 1 VA, but the VA can technically do several voices. They're not limited to just the one, you know?
