Pesky zoo creatures

There's no point in explaining this game - you'll work it out straight away. Suffice it to say, it's still brilliant despite having been away from playing it for a couple of years. (It was featured in the glory days of the Very Friday Email, you see). As a rough guide for your progress, I've just had a stab and managed 15,510 points.
