Update v20180913:

Due to popular demand, Sandbox Mode now has everything unlocked by default. So that means creatures like the Dragons and T-Rex can be placed in Sandbox Worlds with wild abandon! The same goes for special characters such as the Minotaur and the Cyclops.

Character customisation is also fully unlocked in this mode, so enjoy making loads of whacky characters to play as.

Oh, and a bunch of bug fixes that we've toiled away at.
