Game 2X speed

This data pack will speed up your game by 2x! Crops, mob speed, the game itself, and even you will be doubled. You can set yourself a challenge by completing the game. Important! When you launch a world, you'll be prompted in chat to set the game speed to 40 ticks (2x). To do this, set the option, click the message in the chat, and confirm the command. Also, set your field of view to 90 to prevent your screen from being stretched too much.
