Not Original
The reasons I gave this a 3/10 are as follows:
Originality: 0/5
There are so many 'Kill _____' games on NG, this didn't even make me smile.
In a remake of this, add some interactivity, not just buttons and animations.
Art complexity: 2/5
I can make all of this artwork by using GIMP for about 10 minutes. Including the animation. Actually give it some style next time, like hand-drawing the Death Star or something.
Needs Improvement badly.
