## Technical notes:

The playable well is 10 columns by 40 rows, as per the guideline. It is stored

in a x10 by x30 region of memory starting at @well. Each row is x10 bytes, with

the playable well in columns (x03, x0c), so the three bytes at the start and

end of each line are not usable and form the walls.

The high nibble of each well byte indicates the block state (for gameplay

purposes), the low nibble indicates the block type (for drawing purposes).
