"Overall" is an average. 5.5 rounded up.
Graphics - Very well drawn! Didn't leave much to be desired except for the headless scientist. 8/10
Style - Gag endings don't go over very well on me. Also, as stated before, some minor errors such as X-19 being built outside the cryo-tube then suddenly being inside it. 4/10
Sound - The music and sound effects were above par.. up until the ending. 5/10
Violence - Headless scientists, blood, and the threat of a massive nuclear explosion. Nice. 4/10
Interactivity - At least I didn't have to right-click and press Play, but a Pause button would be nice in future. 10/10
Humor - Ha, ha, very funny. You actually had something pretty good going on for a minute. 2/10
Overall - Good start, bad ending. No more of this in future, please. 6/10
