Just updated the demo
It makes a couple important changes.
Ability Bonuses
When you get allies they will have the additional effect of improving your ability scores. These bonuses only last while that ally is in your party. Different allies will give different kinds of bonuses, and (this part is important) they will only show once you have three or more of a particular kind of ally.
New Ending Screen
If your character dies, there is a new screen that shows. It should also allow you to start up a new game once you get back to the start menu.
Other Stuff
I was able to fix a lot of little bugs, add some more artwork to the overworld, and adjust some dungeons as well. Most of the changes are not actually relevant to the Demo, as a lot of those locations are off limits for now.
