Mr. Driller/Walkthrough

When you are first ready to dig, you will need to dig directly down to the air tank. From here, your task is to reach the bottom as quickly as you can before you run out of air.

Mr. Driller has two modes - a beginner course that leads to 500m, and an expert course leading to 1000m. The play field is 9-blocks wide, and allows viewing upto 12 blocks vertically.

Blocks
In Mr. Driller, the levels are filled by blocks. The common blocks are one of four colors, and will link with other blocks of the same color.

When you drill in one of four directions, you will remove all linked blocks of the same color. Any unsupported blocks will shake for one second before falling downward. If the falling blocks pass beside a block of a same color, it will link with the other block instead of continuing downward. When a link of four or more blocks hits the ground, it will disappear - but any supported blocks will drop instantly.

Brown blocks, also recognized by an 'X' on them, are more dangerous. They require multiple drills to pass through, and consume 20% of your air when you break them. Unlike common blocks, only the brick you drilled through is destroyed. However, they can still be destroyed as a group by causing them to fall.

If a block lands on you, you will lose a life. If you are only part-way into the falling block, you will be knocked back and stunned for a second.

The final glassy-green block at the bottom marks your 100m dig. Removing it clears all blocks and items above, but does not replenish your air.

Beginner course
The beginner course is a 500m run to the bottom:
 * 1) The first 100m has four block colors, and an introductory section that shows the different block types.
 * 2) The next 100m has three block colors.
 * 3) The third has two colors.
 * 4) The fourth has four block colors, and air tanks are always shielded in four brown blocks.  Air also drains a bit more quickly.
 * 5) The fourth has three block colors, and air tanks are always shielded in four brown blocks.

When you reach the 300m marker, the air tanks are enlcosed within brown blocks. It is not recommended to drill through them to get the tank; instead, either drop a set of three or more brown blocks on them, or dislodge the blocks to the left or right of the air tank.

Expert course
The expert course is twice as long, requiring the player to dig 1000m into the earth. It has 10 levels:
 * 1) The four color with introduction
 * 2) Three colors, with sealed air tanks.
 * 3) Three colors
 * 4) Four colors, with sealed air tanks
 * 5) Two colors
 * 6) Four colors, with sealed air tanks
 * 7) Three colors, with sealed air tanks
 * 8) Three colors, with sealed air tanks
 * 9) Four colors, with sealed air tanks
 * 10) Four colors, with sealed air tanks

Completing the expert 1000m course will show the ending cutscene and credits.
