I was able to connect this time. Got to a point in the tutorial where it gave me a pickaxe and told me to mine some rock in a cave. So, I clicked a tile and chose "Mine downward." After 15-20 seconds of my guy's mining animation, the tutorial told me "You should now see some rock shards on the ground. If you were to mine this space 50 times, the cave tile would break." Yeah, 50 times 15 seconds to mine through a single tile? This is not the game for me.
