Chicken Shoot secrets

[Noob]

Does anyone knows any secrets or hints of Chicken Shoot? I've been playing Chicken Shoot demo a real lot and found out there are some tricks. For example, what does a _big_ airplane mean, which, sometimes (very rarely), appears on the screen on the _foreground_, flying fast from the left to the right or vice versa. It doesn't give any score when being shot...

There are hundereds of secrets in the full version. e.g. it is very difficult to reach the bonus level.

it seems I get +5 every time I shoot on the pig farm board in the first level.

I found out that you will get also some points if you hit the periscope of the submarine in the 3rd level. The submarine raises and then shoot at it. You will get also points.

Other tips?
