That old-school flava
I remember playing a game _very_ similar to this on my old PC... CGA graphics and everything, I'm guessing you modeled this game after that one. Pretty good. Couple of gripes:
1) Completely silent. It's fun gameplay, but c'mon, not even one explosion?
2) "Backwards" controls. Anyone who's played a flight sim has built-in instincts - press the down key, you're pulling back on the stick, and your plane goes up - press the up key, you're pushing the stick, and you go down. Could you add an option under your "Options" menu to flip the up/down controls?
Nice, simple, small - good entry. If you're going to take on "Madness Redeemer" and make it into a game, you'd better make a _great_ game, because both Combat and Redeemer were sweet flicks.
