Steer Bertie across the minefield with nowt between you and eternity but a mine-detector.

The only problem is that the mine-detector doesn't tell you exactly where the mines are. Your chances of escaping alive are slim, to say the least. The likelihood of your playing the game again is even slimmer.

Bertie must collect UFOs and escape to his home planet. I didn't even escape from the first screen. Strangely compulsive for a while, but the game depends too much on luck and is very slow.
