I've wondered that too
I think I might have heard audio like this before, but it's really very well done. It is a question that I have always been thinking of. If rocks are strong enough to destroy scissors, then shouldn't they be strong enough to destroy paper? It's kind of a Catch-22 or rather, an avoidance of it. It's a system where you need to have different things that add up to each other, but they don't do it very well. I guess it simply has to be done to work in a game like this.
I loved your cute little panda avatar at the end. It was also great to see all of those fantastic pictures you showed throughout the cartoon. Your voice is just so perky in this and you get a great sense that you had tons of fun making this. There is just always something going on or showing off in this cartoon even if it's still images. Thank you for something so nice!
