I have a better description of the game:
-You are a recruit at Intergalactic Military Headquarters and must defend Earth and its allies from alien invaders.  As the game progresses you advance in rank and earn new ships.
-The game is structured by missions that you must complete to make progress.
-All of the missions will be side scrolling
- I will probably have one program for initiating variables, menus, mission select, etc. and one subprogram for every mission.
-If the subprograms don't take up too much memory I might add side missions, but that's way in the future
                  ...That's a big to-do list

In case anyone's interested, the download for the flying engine is http://www.ticalc.org/archives/files/fileinfo/437/43745.html
The collisions are a little buggy and there is no hard level.
Or the attachment is here

This looks like a really fun game.  Especially the new concept.
 

I have almost finished the flying engine, and also turned it into a minigame.  The only things that need work are the menu, obstacle generator, collisions, and difficulty levels.
