Mining

Pixel World is fun because of its unique mining. Even though there are lots of large blocks, mining one causes it to split into 16 pixels. This allows for less blocky building and mines.

Techniques
There are actually quite a few techniques for mining. Here is a list and explanations following:

Quarrying
In this technique, the player digs straight down in a large span of blocks (usually in a flat area), hence the name "quarrying."

Shaft Mining
When shaft mining, the player digs diagonally downward until deep underground, then starts to dig left or right, creating a shaft.
