The player can now dig tunnels! (v0.2)

The player can now dig tunnels!

For this purpose a new collectible item called "drill" was introduced which enables the player to remove one wall element by bumping into it.

Here I overtake several other runners by digging through 2 walls:

This was a huge shortcut! :-)
