One lazy Sunday afternoon it happens - a bomb drops through your ceiling and on to the floor. The timer is ticking away. It reads T minus 60 seconds and counting. Just one minute between two and the complete destruction of England!

Can you stop the clock by selecting the correct colour combination with a series of blasts to the organic brain of the bomb? Time will tell.

Use the Z and / keys to move left and right and the space bar to fire the blaster. Andrew Wills of Aylesbury, Bucks, provided this adventure.
