Looking glass

[3elDU]

Add a "looking glass" button, with which you can point at any block in the world, and it will show help and description on it. Those tooltips should help new players, but they shouldn't spoiler everything right away. A player still should think for himself.
Example: You hover over sand with stones
Tooltip: Wonder what these stones are? Try to pick them up.
A player will try to interact with the block, and thus, will discover new materials and game mechanics.
