Backstory: A world of Minecraft is currently being created but you found a way to get into it in the process. You found a cave full of diamonds that you keep mining and gets created again. Use arrow keys to move. Click on the diamond ores to mine them. You have to get close to the diamonds for it to work. Also every 5 seconds, a zombie will appear in the cave, but you can also attack them. Try to beat the Most Diamonds and comment on your score.
This has to be my number 1 favorite project (so far).
