Super Mario clock

Thanks everyone for having look on my watch face.
@Gordon, thanks for your suggestion, I have reduced the image size and it is now much lower.

As a next step I am trying to animate mario jump. My code is available as APP here .

When you press BTN1, mario will jump. But I am not happy with the jump animation performance on actual clock. It is bit flickering.

An in othr example, like Flappy Bird, Horse Race, or in Trex, animation is smooth.

Any suggestions to make it better?
