Several levels adjusted including adding the key to a couple will be integrated better in the future

I had a lot of issues since it had been awhile since I had worked on the game, behind the scenes a lot of code was sifted through, changed, reworked or thrown out. The amount of stuff added and changed was less than I would of liked because of this, but i still managed to add a couple things.

All and all I'm happy with the work I got done, and hope this is the start of me getting back into this proper.
