Played more Terraria. It's a fun game, but I'm losing my interest. Can't find nearly enough copper or iron. Nothing is really progressing. I've explored one entire cave system and another down so far that the game started changing the music. In both instances, I got so lost, I had to dig my way out. That's conceptually kind of cool, but it's just a lot of time digging dirt. And I got very little for my efforts. Oooh, I found sand. You know what I can do with sand? Make glass, then bottles, then a few potions I don't really care for.
