Postjam improvements

Hey hey, something wild happened, Help I cast the wrong spell scored 2nd overall in Ludum Dare, and 2nd most fun! This is like next level insanity, and to celebrate, I've remastered a bunch of the levels, squashed bugs, and made a proper ending. This should address a bunch of spots people were getting stuck at, including the final crash =P

And wowsers, what a result eh? Thanks to everyone who played and rated, and big thanks to my musician friend ClockMaker, and to the almighty Dim who made sounds. And thanks to the folks from discord that helped play test!
