This game is horrifically bad, with literally nothing to recommend it.
Except for the graphical fidelity, which is crude enough, it would be considered shovelware on an Atari 2600.
Let me explain the game play. There is a crudely drawn airplane that you move from side to side against a non-scrolling background. By clicking the left mouse button, you shoot at another, equally crude representation of an aircraft that moves from side to side mindlessly. Every time you hit, you get 10 points. There is a time limit. At the end, it displays your score, with a samll comment on it with a button to restart, as if you'd actually play again.
That literally is all there is to it. Aside from some terrible looping music, there is nothing. No sound effects, no animations of explosions if you hit, nothing to add any appeal to the horrendous gameplay.
In short, do not play.
People should do better before they upload.

Don't play XP

OMG THIS IS WORSE THAN MY GAME >_<

Nothing interesting about this. Got bored after firing twice and realized that is all there is to the game. Maybe add levels, more planes, powerups, better graphics, etc. Also sometimes it doesn't give points when you hit the enemy(?) plane.

This game definitely looked like fun. Unfortunately, what I got was simplistic gameplay, shoddy graphics, and bad programming. A definite skip.
