Eternal Red - Flash Game

* First map, which is the three floored with sentries and panels has
  about 74 levels till you beat the game.
* The cash gun is like the machine gun turret, but it gives you money
  when it hits a monster, depending on the amount of upgrades to damage.
  10 upgrades = 10 dollars per hit.
* And a slow panel as the first panel with an acid sentry above and a 
  machine gun behind it will decimate the monsters.
* The final thing is: the sooner you kill an enemy (measured by distance,
  not time, hence the slow panel in the front), the more cash you get.
