A new ending!

I just reworked the ending to Habilis, after watching a lot of people play I feel like it was a bit too abrupt.
It needed more of a finalized conclusion for Nathan. I think it's much better now. Also special thanks to my kid for help with the idea.

I also fixed a saving bug in level 3 that made you get stuck.

Thanks guys! I do listen to feedback and apply it.
