My first Rube Goldberg! Rate it:

10 if you think it's perfect/legendary
8 or 9 if you think it's great
6 or 7 if you think it's good
5 if you think it's okay/average
2, 3, or 4 if you think it needs improvement
0 or 1 if you think it's awful/horrible

I don't think I can make it any longer, and, I am afraid that
scenes should be interactive, like, make a user do at least
one thing to prove that it's interactive. Go check out
Ultimate Rube Goldberg, the author of it does the exact
same thing, he makes you do one action that creates a
chain action spring that'll make you hooked into it, but I'm
afraid I can't add much in, so sorry.
