Well, the first thing I noticed is the graphics are huge, borderlining ridiculously big.
Second, the jumps. From what I see in that video, they just don't make sense. The height of it's jump is roughly size the size of it's body, which means that even with multiple jumps, it's vertical jumping power is almost worthless, especially when metal (unless it's over an Alloy, in which case the metal isn't a problem).
Lastly, the aerial control. I know that being able to have high control makes some sense considering the character, but that's overdoing it. I would change the Jump H Initial Velocity to 1, and the Maximum H Air Velocity 2.5. That still gives you that control, but it won't just flop around anymore.
But of course, that's just my opinion. It's your character, so you do what you want with it.
