Experimental Gameplay

Experimental Gameplay is a game option exclusive to. When enabled it allows players to test some unfinished or work-in-progress features. It does break your game after an extended amount of time.

Toggling
Experimental Gameplay is found in the world options when creating a world. Turning the option on does not disable achievements, however it can't be disabled after the world is created. Enabling it on an already existing world makes a copy called "[EX] World Name". The original world without experimental gameplay can still be played, although progress does not transfer through the two worlds.
