I can't believe these are not intuitive, but:

How do you eat bread? I click on it and it picks it up, but how do you consume it?

How do you equip items? I can see them in my inventory, but when I click on them or the slot they go in nothing happens.

Is there any way to make your character(s) run?

Thank you!

Well, I found and RTFM. For those with the same questions:

Drag the bread onto your portrait in the inventory screen

Click on the slot then double click on the item. Problem was I bought stuff I could not equip.

Double click then hold down the mouse button.
