Use the arrow keys to move Felix and Zelda over Nazi's and into Haystacks. Collect carrots, each one is worth 10 points, but if you touch a Nazi, they steal your carrots and you get -10 points. Touching them will also send you back to the start. The instructions are also in the game.
Based on the book 'Once' By Morris Gleitzman. This is a Demo only, so that is why there is only 2 levels, and they are REALLY easy.
