Minecraft is an awesome world of imagination, there are a lot things you can try out in that game. Let me show you the basics, there are two modes called creative, and survival. Creative mode is when you have unlimited resources, and you can build whatever you want! In survival mode you have to get the resources yourself, and you can get chased by zombies, and skeletons!
If you are very smart at building things, and mechanics you will definitely will love redstone. You can build an elevator, stopwatch, and a automatic door! If you think that is cool. There are endless possibilities of what you can build with this red dust, this resource is amazing! If you are a beginner still try it you won’t regret it!
You should got to the end when you are a really experienced person on minecraft, you need an enchanted, diamond sword, splash potions, and beds to kill the Ender Dragon which is the boss of The end. The bed is for exploding the Ender dragon because in the end beds explode. After you killed the dragon you get its egg, if you touch it breaks,but I will not tell you how to get it to the overworld, I want you to experience that yourself.
Conclusion: There are more portals in minecraft, but I want you to figure them out yourself, Minecraft is awesome!!
