Gaming A slightly old game.

[Westside]

I want to know this online flash game that I used to play. It's a dude that travels the solar system with his dog to defeat aliens that would destroy the earth or something. Each planet is really strange, I remember one of them had cows. They have levers and switches that lead to doors and stuff to solves puzzles. Does anyone have any idea?

I also believe the dude had an Australian accent.
