I'm still working on the full game, but I have updated the demo to make it more clear! In particular I've

1. Shortened the intro. This part doesn't make sense outside of the full game.

2. Added a countdown timer. This allows you to know how much time you have left.

3. Made the ending more clear. The false ending last time was too confusing since it was just meant to be a brief test for the demo.

Thanks to MixoNat for his feedback -- most of these changes were because of his suggestions.
