To beat Minecraft first I would start by getting wood tools ( sword, axe, pickaxe )and then getting stone tools. Then search caves for iron and get full iron armor and tools then look for at least 3 diamonds and with that make a diamond pickaxe. Then get a water bucket then I would look for a lava pool. Once you find one I would place the water and let the water cover the lava to make obsidian. Then mine the obsidian and get 12 pieces of obsidian then make a portal then I would go through it then once in the nether.

I would look for a Nether Fortress and find the blaze spawner and kill the blazes to get blaze rods at least 8 blaze rods. After that I would go to a Warped Forest in the nether and look for Endermen I would kill the Endermen until I get 12 ender pearls. Once I am done with that I would go back into the overworld.

then make ender eyes after that I would use the ender eye to lead me to the Ender Portal. Once I get to the Stronghold then find the portal then I would put the ender eyes in then go through once in the end.

I would go over to the Main Island and then go up to the towers and break the end crystals once I have broken all of them I would go to the Ender Dragon and. keep hitting him with my axe until he dies and then I would get the Dragon end and go through the portal and then you have beaten the game.
