Welcome to you, new Blackvoxel player.
Here are the tutorials and the game missions. We recommand all players to follow it.
Of course, if you are a very experienced player in sandbox survival games in the search of difficult challenges you could discover the game by yourself with the only help of the game manual. But you should be careful as Blackvoxel is VERY different of any other voxel game.
Blackvoxel is a game about automation, not a game about doing thing by hand. In Blackvoxel, never do things by hand. You'll have to learn some new logic.
If you encouter any problem in these missions, you can post in the forum to get help.
