Interesting!
That's a cool concept for a game! Finally, something new and original!
Anyways, it was a fun game! Based on the speed of the game, I think it would have been beneficial to be able to shoot faster, or just increase the distance moved by the kickback.
The graphics were nothing new, but they fit the theme well, and weren't hard on the eyes.
The music was great! And the sound effects fit well too!
I wish there was a little indication, just something that changes slightly, like a light, whenever you shoot. Its not necessary, but it would be cool.
Nice game! 8/10
