Okay so when I started mc i was on the demo version:
1.tried to hug creeper
2.mined stone with hand and thought that stone was only available on full version so i bought the full version
Actual mc:
1. Mined straight down cuz a video said to
2. Thought a diamond sword was bad so i traded a dia sword for a bow
3. Put TNT as a floor
4 put lava next to wooden walls
