Oh yes I have a tutorial based around doing sounds! This one was more focused on doing UI stuff.
But having a part 2 of the tutorial for making it sound nice would make sense! Making a main menu screen, end screen, options, sfx for like the cards being shuffled, stuff like that, does make a lot of sense! That way if this is the only tutorial they want to do, they are taught how to do that stuff and can build off from there.
"Here is meat and veggies of a deck builder"
"Here is a little bit of seasoning!"
