First, the mockup!

Anyway.. the simple concept is you are controlling a fleet of the last ships of your race.  You are fleeing your planet as an alien armada of doom approaches.  You will be able to move your fleet up/down/left/right and there will also be a key that lets you toggle the density/pattern of your fleet.  Think of it as able to expand or contract.

You will move through the armada avoiding colliding with capital ships and what will surely be horrendous energy weapons fire as they attempt to anihilate your race.

You must get a least ONE of your ships through the armada to win.  The more ships you get through the larger your bonus at the end for saving a larger gene pool of your race…

Simple idea, hopefully the scope will be one of which I can get a fun, playable game out of before the deadline is up…
