Experimental Gameplay

Experimental Gameplay (also known in-game as Experiments) is a game option exclusive to. When enabled, it allows players to test some unfinished or work-in-progress features that would eventually be released in future updates.

Toggling
Experimental Gameplay is found in the world options when creating or editing 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 adds an "Experimental" tag right next to the game mode name in the world menu. Once the experimental world is created, it cannot be turned off again.

Warnings
The point of Experimental Gameplay is for the player to look at some not-quite-finished features, which could crash, break, or stop working at any point in future updates. When the player attempts to load the experimental world, it will show a warning message before loading it. Attempting to disable experimental gameplay toggle via external tools could also crash and break the world.
