Item description:

Remember: Never drink mixed, but stay with one drink. Otherwise
you'll have a terrible hangover the next morning!
Swap two drinks on the playfield in order to make a set of three
or more identical beverages.

Joypad ............................................. Move cursor
A + Joypad ......................................... Swap drinks
START ...................................... Pause / resume game

Move your cursor to one of the drinks, then press Button A and
a direction on the joypad to swap it with the adjacent beverage.
This will only work if you create a set of 3 or more identical
drinks, which will disappear, and the tiles beneath will turn
from grey to golden. New beverages will fall on the playfield.
The game continues to the next level when all background tiles
are golden, and end if you run out of time.
