I played the free version for all of five minutes. I was building a glass pyramid when I accidentally deleted a block of dirt and fell into a small cave underneath. Suddenly my glass pyramid had a bonus tomb! Then I immediately bought the full version.
Right now I have a cute little lake house with a huge lighthouse not too far away. I haven't played in a while though because I killed myself while pouring lava into the lighthouse light and I just can't be bothered to make the trek all the way from my spawn point back to my lake house.
