I like the idea for the controls! I think the game would feel more satisfying if there was more visual feedback on scoring points, something simple like floating numbers above each ship showing how much each of em are adding to the score!
You could also add little bonus challenges, like “the closer two ships are without colliding, the more points they each give”!
I see alot of ways you could build ontop of this game, which means its a very very solid base!! And the music was very charming!!
Good job!!
