Hi! Thanks for playing! :)
Regarding voice acting;
Originally I was going to do voice acting, but there were a few issues. Sometimes, if the voice actors aren't competent, no voice acting is better. They can also be quite expensive for someone making a short indie game.
I also think having just text makes it easier for people recording the game to read it instead of having someone speaking over them every 2 seconds (since, as you said, there is quite a bit of dialogue).
Some games can definitely benefit from voice acting, but personally I decided to not include any (apart from the TV) in this project!
Tho, my next project will definitely include it. It's a great tool for building immersion and character!
