I've added a demo for Windows and Linux users.

Obviously, it's limited so in the demo version there is only 1 game mode (instead of 3 in the full version), also you can't enter your name into the high scores table.

As mentioned in the title, I've also added some improvements to the game.

• I've improved the look of the customer's shopping list, including graphics fonts and also made some of the text a bit clearer to understand.
• I've added a roof to the supermarket. 
• I've tried to make the products fling forward a little more when the duck hits them with its wings at full speed.

Have a play and tell me what you think!

QUACK QUACK!
