Very nice game and quick to pick up! I am also a fan of the shader effects as well as the speech samples, cool.

Excellent use of aesthetic overall in this game.  The sprites themselves may be quite simple, but the way in which you use those graphics is what really wins out here.  The presentation is top notch, polished to a mirror sheen!  The projectiles feel a bit too slow moving for the much higher resolution we are dealing with in modern hardware.  It's a very faithful recreation, I only wish you pushed the gameplay concept a bit more.  Even still, this is an excellent jam piece!

I never played the Atari 2600 game but this was pretty fun. There's something to be said about simplistic controls. I really dig the graphical effects. It took a minute or two to get used to the controls, but after that, I was good to go.

Nice game :) I really liked the aesthetic of it, especially those backgrounds. The music was good enough to keep me engaged, and i liked the way the the level progressed, more and more difficult AI came at you with more civilians to save in each level, i also adored the transition between levels.
My only complaint are the controls, i found it really hard to hit left, every other directions it was snappy and quick, this was fine in earlier levels but became really frustrating in the later levels.
All in all, a REALLY REALLY good game.
