Pretty good
The whole little movie was really good. The art was pretty simple, but still really enjoyable. The concept is 100% true.
The only thing i didn't like is that you made "Jim" (the character) just mug people when he got power, although he could mug them even without power. If you had made him do other "Jerk"-ish stuff instead of that, you would have gotten my 10/10
Overall 9/10
Keep it up mate
