First tip. Punch trees. Second tip. Read the Minecraft wiki. There's alot of good information that you can find on there about blocks, crafting recipes, brewing, enemy mobs, and etc. For your first world (and your first night), I recommend gathering as much wood as you can and craft a crafting table. After that, make a wooden pickaxe and a sword as soon as possible. Your first night might also have you hiding in a hole in the ground because zombies, spiders, skeletons with bows, and creepers (the green exploding thing) all spawn at night and let me tell you, they are a little less than friendly. Also, I would try to find some coal as soon as possible on that first day so that you aren't caught in the dark. Certain blocks will look a certain way so normal stone is just the simple gray block. Coal will look a little like that block but it would have specks of black on it. If you come on the MC server, I'm sure everypony on there will help you get orientated or I can hop on too and give you a hoof myself. I hope you enjoy the game. It's extremely fun once you get the hang of it. If you have more questions, you are always welcome to give me a PM.
