but jsut remember its fun at first but after first boss you are going to constantly have to run back and forth to insanity trying to mine and since ores weigh so godamn much its a pain. that and the constant attack from monster that always know where you are and never ever give up their hunt. other than that its quite fun game

This is why it's good to build near a few copper veins and if possible near the shoreline with some tin + future boating. Just need to manipulate the terrain a bit to make it impossible for enemies to attack you except perhaps the odd troll in which case you'd want to fight them outside your base.

Then when you find a decent swamp - set up a small base on a sunken crypt for iron. Mountain you can either set up the base on the mountain or near the base of it in which case you'd want to run down minerals + use portals to get back up. Maybe even use a cart with some decent pathing.
