My sister is working on a visual novel. we wanted to use unity to build it. she wants to have video's with buttons clickable to skip to other scenes. problem is we both are noobs! do you guys have any tips on tutorials or anybody knows if this is possible. and what would be the best method to tackle this.

I figured having each scene as a mp4 and having buttons trigger each mp4. but, how would that work with time triggered Audio.
