Final Demo Release

Hey everyone! This update to the demo release isn't the largest, but it should be the last. With the newest additions to the game's music and sound effects, the demo is now complete, or at least, in the state it's intended to be in prior to the release of the full game. In other words, anything still wrong with it at this point is now our screw-up rather than a temporary omission.

We're still happy to take feedback on the game, and further adjustments are possible, but if anyone's been waiting to check out the demo until it's properly done, now's the time. And if this is the first time the game is being brought to your attention, I hope you enjoy it; we've put a lot of heart into this one.
