To whom it may concern,
The idea of surviving in a thriving in a eco system sounds like the greatest thing ever. And I'm going to be recording my entire experience. Although I think that to test and understand the many mechanics of the game players will be at a loss as to how to do so without destroying they carefully manicured worlds.
So I propose to have a game mode in which you can use all the items in game so players can test and build to their hearts content with out the fear of hurt the cute little bunny rabbits.
