I've reached the point of no return in Bastion's story. I know that there is a New Game+ option, however, my decision on whether or not to go forward with the story at this point hinges on what is kept and what is reset. For example, I don't want to drive myself crazy trying to finish all the Proving Grounds if they're just going to be reset in New Game+.

I'm currently running on the assumption that your level is kept, but otherwise, I'm unsure as to what all resets. I'm wondering about:

• Vigils?
• Proving Grounds?
• Weapons and their upgrades?
• Buildings and their upgrades?
• Accessibility of Secret and Weapon Skills?
• Who Knows Where progress?
• Items in my Pack?

Please feel free to mention anything I may have forgotten that is not included in this list.
