Flash Game

We are web development company based in South West Devon. We provide a range of different service ranging from CMS sites through to interactive, dynamic Flash sites. One of our clients has asked to have a game added to their site, the idea being that customers can compete on a high score board to win a prize. The company in question have asked for a Wind In The Willows themed game, the actual game is entirely up to you. Our initial thoughts were to develop the game in Flash, but again we are open to suggestions and if you prefer to use a different platform this is fine. The only real requirement is that you have experience in developing games with a portfolio somewhere or examples of your work, and that you can link the game to a score board so we can keep track of who is scoring the highest score via their email address.
The game does not need to be complicated or have amazing graphics, the usual flash stuff out there is just fine, but it must be Wind In The Willows themed.
