This character is full of wasted potential. Let me explain: First, the idea of having Jerma as a character would have worked if he was mostly a zoner who attacks from afar thanks to his baseball bat (similarly to Fang).
Second, the elephant in the room, i.e., its size; it would be better if it was the same size (or maybe bigger) than the vanilla cast, so that it doesn't get stuck at various points in the stages.
Finally, the last thing I have to say is that the choice of the Green Screen is decent, but it could be improved in many ways.
