About the game

Another oneliner attempt for the 2007 compo. Based on a game I remember typing in around 20 years ago from a book I borrowed from the local library, an Osborne computer book. My only oneliner game to contain sound and a significant number of UDGs. This game is so simple, it's a natural oneliner. There was no danger of exceeding the allowed space, and as such I was able to be quite liberal with the use of code.

Rules of the Game

Your aeroplane flies across the screen from left to right, getting lower with each successive pass.
Press any key to drop a bomb on the city. You can only have one bomb at a time.
To win the game, destroy all buildings, and land the plane safely.
If your plane hits the side of a building then the game ends. Try again with the RUN command.

Notes on improved version

Thanks yet again to Einar Saukas for greatly improving the game as follows:-

Added a solid ground for the plane to land on.
After you have landed safely, you now go on to bomb another city, and can increase your score.
Graphical crash effect using FLASH and a sound effect on crashing.
Made the BORDER colour cyan to match the in game sky colour.
