It took me a little bit to understand that each of the asteroids have gravity and you can only move around them. Once I got that concept down, I was zipping all over the place! I did feel a little crowded. I would suggest making the character and cat a bit smaller. That might help give the player a little bit more room to move around and provide a more time for the player to get the cat before it hits the end of the screen. It's a fun, short game!
