Game inspired by Asteroids

Some years ago i wrote a couple of simple flash games including a few remakes of classics like Asteroids and Tetris. I thought it might be a good idea to update some of them to make them work on smartphones (assuming the games will be playable on the small screen) and tablets and - of course - to make them look a little better. This is a drawing showing some of the updated graphics for the Asteroids style game.

Asteroids!
One of my favourite games.

That's great artwork.
