Have you ever read the famous works of Gulliver’s Travels, where he both shrinks to the size of an insect, down to just a mere several inches and grows into this monolith of a man, a massive and towering sky scraping giant? This is a famous story and has been replicated many times including the cult favorite Army of Darkness and really uses some great ideas from the simple idea of growing and shrinking! If you think that idea, the transformation of a human is a cool idea, then you should probably really check out this mod for Minecraft right this minute! You can transform yourself and even mobs, creating a much different feel to fighting the deadly mobs, making them stronger when much larger! You can also use slime and paper to fly and climb walls, making even more awesome features to get around the new world perspective.
