Whilst working as a senior test engineer for one of my past employers we were developing a new internal application to allow us to easily execute and record the outcome of manual functional test cases against our various software development projects. At one point someone had made the suggestion that we include an easter egg in the software, space invaders was suggested and someone would likely have put it in eventually... however a new opportunity presented itself.
The test manager at the time whipped up a banner for the application (included below) which became the subject of a few jokes. I kept saying that it looked as though the person holding the magnifying glass was about to tilt it ever so slightly and focus the sun and burn the little people alive. Others suggested that they were about to swing it down and squash them. I took these comments and combined them to make a replacement for the banner to use as an easter egg that showed up only on a certain page.
The game is very simple, move your mouse along the banner to move the magnifying glass. LEFT CLICK to tilt and focus the suns rays into a deadly inferno, you may hold it down if you wish and drag the hot spot all around the banner.
If you focus the magnifying glass long enough in one spot it will start a spot fire which will continue to burn while you move away. You may start a number of spot fires and leave them burning, they will eventually burn out however the amount of time they burn depends on how much longer you continue heating the spot fire after it starts.
After you start one spot fire you can drag very slowly along to utilise it's heat in lighting additional spotfires faster than you otherwise could, this chain of spotfires will eventually start following your magnifying glass creating a wall of fire.
There is also the secondary attack... DOUBLE CLICK to flip your magnifying glass on it's side and swing it down to crush those who may be beneath it. You can drag the magnifying glass along while it is down to maximise your damage however you will need to be quick.
Keep an eye out for Larry the fire warden in his red firemens cap and yellow coat, he will extinguish your fires when he encounters them. He is impervious to your fires and focused light and simply laughs at your attempts to set him alight...
There are a number of bonuses in the game that add to your score. From having very few people left through to having a full length firewall, killing the fire warden and picking on particular people.
