Based on the VIC 20 classic Blitz, the C64 original of this little game was actually written for Jason's mum to play after the keyboard (and in particular the space bar) on his trusty white breadbin breathed it's last and couldn't run it any more.
The game itself is very simple; your spaceship is running low on fuel and needs somewhere to land and the only place anywhere within range is a deserted alien city. As you make repeated passes, getting lower each time as the fuel decreases, you can drop bombs to flatten the city with the space bar or a joystick fire button and make it relatively safe to land on.
Trivia: The source code for this version was built from a disassembly of the original C64 version which was then improved and ported to multiple 8-bit platforms. Released as part of the 2014 New Years Disk.
