Here is a very much not comprehensive list of (not) all the changes.
The delay for when you wanted to get up from a sit-able thingy is now removed (I figured out how coroutines work :p)
There's more text explaining things that apparently where in need of being explained.
Buttons now do button things, like clicking noises and pressing up and down.
More sounds added! And some fixes too.
That's it, I think, you're welcome.
