Using information that Keith provided I discovered some more stuff about this game. This game seems to be part of a trilogy of games, and each one seems to cover a small part of the series but, how much, I don't know.
This one is the first in series, and it's possible it only covers Sandleford warren, possibly up to the part where the rabbits escape. The next game seems to be about reaching their new warren. The last game I haven't found anything about.
