If you explore further to the east of the house, you'll find a bridge that takes you back into the woods :). On hindsight I suppose that might not be entirely clear, with the trees and bushes being pretty thick east of your encounter with Rosie, especially when that house and crops kinda draws you to move south.
Sorry if the 'a' key was still buggy, I did what I could to hunt down those bugs, but I guess one or more must've still slipped through. Whoops ;).
Thanks for all your feedback, glad you enjoyed the game!
