Seeds!!

Worlds can now be saved through seeds!! This is the main thing i've been working on, along with adding a few little things.

-Seeds have been added to the game

-Map size has been doubled (again)

-you can set the seed in the menu

-you can set your starting speed and strength in the menu too

-wheat has also been added to the game, but serves no purpose

-torches have also been added but also serve no purpose
