Hello!
For the first question you may do that if you wish, but it would count towards the 1000 word limit, as it would be considered "author's notes". We understand some people may want to release that information for the player, and so that's why we allow you to put that info in the game page. I'd assume you would want to use your 1000 words in the story instead of your notes, so I'm going to recommend you leave those out of the game and post it on the game page.
For the second question, this would not be allowed. The "beeps" ruling has been added for the times when one does not want to have a VA but still some "voice". So it's meant to be either one or the other, you can't have both, or try to replace the voice effect for a secondary voice. Effectively they are doing very different things, so it'd be bending the rules too much. However, thank you for asking!
This has an easy solution, though: You can have a VA doing different voices!
- can use use variations of voices
- can have their voice modulated and processed to create completely different sounding voices
So hopefully this should solve your problem.
Happy jamming!
