Time Traveler?! YAY!!!

     I wish we could play Minecraft Alpha again, at least we still have the Marketplace content though. It would be exciting to add a setting where you could change the version of your world. If I wanted to, I would create an alpha world so I could just see what it was like. I am only a child, so I have no idea how to switch versions. Please add an easy feature to switch versions in your Minecraft world so we could all have fun and see what Minecraft Alpha was like back in the day.
