I like the idea and it fits the theme.
I would have liked to see my score as I’m dodging rockets though. I feel like it would help me wanting to play more. Also, having visuals and audio cues about incoming rockets would be cool. Like a threat indicator or something. You could add a lot of juice to this game by making simple effects when you dodge a rockets or when you come really close to one!
The changing colors are cool but way to distracting as they are now!
Overall pretty cool, congrats for your entry :)
