Extremely Awkward
Well, it seemed like you had the right idea, but it was executed in a very odd fashion. What annoyed me the most was the voice of the protagonist. It was obviously some sort of program and it sounded very robotic and monotone. If you can't voice act, then don't. Please do not rely on speech programs unless you're making a clock/lock movie. The graphics were generally good. There were a few awkward movements and strange tweens, but still, they were decent overall. The dialogue was also very weird. "...with massive mass"? Come on man, word your sentences more appropriately or have someone proofread. The fight sequence was alright, but when the robot smashed the guy's spine, what, five or six times, how is he still alive? Unless he has some sort of super powers, metal crushing against vertebrae equals paralysis. However, despite all the oddities, I cannot give you any less than a 6. It's obvious that you spent a load of time on this flash, so I'll cut you some slack. Great effort, not a bad job.
