Game edited all the way, world map

Game works i'm 70% happy with everything up until it drops off. Made the
world map (field) way bigger and we need to start designing that big ass
piece of land for the rest of the story. given the size the game will be
roughly 6x longer than what i already have done. My goal is for the game
to be 8-10 hours long. right now im at 1hr 15 mins gameplay (take into
consideration that i know exactly what and where to go) total game time
is prob 1hr45min- 2 hrs tops.
