Looks good!
Maybe his landing could be smoothed a bit, but else good job! The movement when he touches ground and stand up to normal stand seems a bit quick (maybe just for my eyes).
Would be cool to be able to ride it haha jumping through the mountains with less falling damage or jumping from higher heights.
Put a particle effect in front of its feet as if it’s kicking up debris as it slides forward, and keep the slide. Also, take-off/impact ring of dust would further enhance the animation.
