Nice idea! There's room for improvement. I think the animation timeframe doesn't sync with the cat velocity. You could speed it up a little bit so it starts faster and iterates through the frames faster. I'm not experienced but if you used the particle system for the meteors trace probably would be cooler if you unchecked the "local coords" box (under the Drawing tab at the particle created). This should make the particles follow the trajectory of the meteor. Great job! :D
