I like the idea, though the game doesn't feel "fair" as it is now. I think my main issue is with the spaceship's "blindspots", where the lasers can't hit. Moving changes this, but not enough to, for example, attack asteroids coming from the side.
A minor issue I had was with the thrusters; it's hard to tell if they've been turned on since the particles take a little bit to come out; in this game you don't want to have to waste time verifying that your input was correct, so this is more noticeable.
I really like the idea of having the blue scout areas! The zoom in/out effects when there are really nice.
In terms of art, I think the main issue is with the inconsistent artstyles; though finding similar artstyles for various elements in opengameart or similar can be a challenge on its own. I'm also very biased towards audio, so I always recommend finding some music and sfx!
Still, it seems like both of you worked on the coding/design? There seems to be a well shared vision, which means there's some impressive teamwork behind the scenes; great work!
