Gamemodes

Creative mode is still not implemented. If you want to enable something like a "semi-creative" mode (godmode and instant digging), you can open the console (^ or ` key, depending on your keyboard layout) and type "setgametype 1" (without quotation marks). Using a 0 returns to default mode
Please not that this is still a work-in-progress mode, i.e. you may fall through the ground more frequently when digging etc. (if that happens, press F2 to enable flymode).
