As I've already said,
Paws & Claws: Pet Vet: Australian Adventures is slightly difficult to figure out how to play if you don't already know what you're doing. The first major annoyance I found was the speed of the vet. There's no way to really make them move faster, so you'll want to use the mouse scroll button to zoom out (and back in when you need to). After you're zoomed out, you'll find it much easier to find your jeep and the sick animals. To get into your jeep, just click on it. You'll automatically exit it when you come to an area that you can walk around in. To drive it and to move your vet around, you use either the arrow keys or (W), (S), (A), & (D).
When you look at the map, you'll see dots on it. The red and yellow dots are animals that you need to heal. You should always treat the yellow dots first because they are the most critical. Yes, I know that logically we think of red as being the danger ones, but here yellow is more in danger. The blue dots on the map are just areas where you can sit and watch the animals run and play and jump. If you want to pull the map up at any time, just press (M).
When you need to order more supplies or check out the encyclopedia or find out anything else that you might need to know, just press (P). Your PDA will then open. You can click on any of the tabs to find your information. Eventually (really it doesn't take that long at all), you'll have people want to come visit, so you'll have to order supplies to construct a guest house. As you progress, you'll unlock more animals to treat, more areas to visit, and more things to build
This game really frustrated me until I got the hang of playing. The controls aren't described very well at all in-game and there's really not a good help system. But once I figured it all out, it's a really cute game. If you like city building games or anything like that, you should give it a try. Just make sure to read the instruction book that comes with the game if you can't figure out how to do something! Most things are described a little bit in there at least.
