Overall pretty good. Nice presentation and graphics, simple gameplay, easy to figure out. I have two cents you can take with a grain of salt: 1) it is missing what I consider the core of classic Lunar Lander (which I feel like this game was trying to channel, but with "more going on"): that delicate balance of gravity and thrust. In classic Lunar Lander the primary challenge isn't dodging asteroids, but just trying to balance the forces so that you land your delicate craft. In this case, there is a lot of "drag" on your ship so it slows down naturally as if it is in an atmosphere, and the terminal velocity is not enough to damage your craft from a hard landing. I was able to enjoy the game more by understanding that you weren't trying to recreate a more complex Lunar Lander, you were trying to make a game about dodging asteroids and dealing with "gravity wells" of moons, planets, stars, black holes while landing. 2) the gravity wells on later levels make the game practically impossible (possibly unwinnable). On the fifth level I had a black hole directly above the landing zone, I couldn't get anywhere near it without the ship getting thrown across the screen.
