I liked it I guess. I'm grading this as a standalone project.
The technology was good, but I didn't like the sounds of the neck-parts moving. It reminded me of a dentist drilling into my teeth.
The animation was good, but I doubt any art went into this. I feel like a person with a third-grader capacity could animate this.
I am not sure about the relationship between the green robot and the setting.
The ending was pretty much a non sequitir to me.
The best I can compare this to is the new Mickey Mouse's playhouse. There's no real story, just an animation engineer showing off the characters. Don't get me wrong, it was good, but even children these days cheer to what little mileage Disney they can squeeze out of their characters.
The whole chasing scene was boring. The commands didn't make sense. The little trap portal made even less sense since this gravity labyrinth seemed to be more of a test chamber than anything else.
Why didn't the purple robot shoot the other one? There was no reaction, just turning around and running away. No time to compute, no warnings or "halt." Just a simple change in direction. Snoresville.
You could have done more with the gravity rotation. I mean, he fell down steps in a gravity controlled environment? Come on.
