I've just received some more useful input from THEBRAINSTER which will help me improve Whac-a-Squirrel even more, so version 2.0c of the game will be out soon. But I'm afraid it will not be available as a download... you'll have to collect one from a pile at the base of the big English elm (at the southern end of Bollock-acher Wood).
I think Berbsterbaby made the right decision to quit... he's just too good for the rest of you. I'm sure he won't be able to leave it alone though
