- You have to be quick in your first night, start by collecting wood, food and other stuff from the surface since it is really not save to stay outside at night
- When night falls try to go below the surface and build a shelter there
- You are never save; even when mining ores certain mobs can spawn, use a pickaxe to deal more to these mobs
- When water touches lava a mob or two will spawn
- There are also dense ores which means that they contain more ores than normal (e.g. if you mine a dense iron ore 3 will pop out)
- Highly recommend adjusting the settings so your performance improves (render distance down, particles off, etc...)
