A simple game, it works, it got sound, it has a quite nice presentation. Actually really like the odd music/space-flight voice thing, it feels like a odd pick for a endless-runner that usually otherwise uses a bit more high-tempo music, but I think it works. It makes it feel like that its actually a space-ship we are flying in a way, trying survive in space rather then a game only about score in a space-themed costume.

Its also nice that with such a simple game-concept, you also made it rather "no-nonsense" in how to play it. No menus in the way, just start playing and when you die, just click to instantly restart.

With that said, It was really distracting that you can see asteroids being spawned in and removed. You should make them come in from outside the screen.

I would also have liked if you added a bit more variations to the asteroids, as right now they fly in a very strait lines down, adding a bit of angle to them would make it feel a bit more natural then it is right now.

Overall, great work!

I love this concept!
