Nice little clone. If I could change anything I would make the ship rotate a bit faster, but I suppose the original game was like that. Also it would be nice to have a "thrust" animation and sound.
Thanks, I agree about the rotation, I will look at that for the next update, I used to have a thrust animation on the ship but I had a problem with it, I think I may have found the solution though so will look into putting that back in!
Thanks for your suggestions, I'm now publishing the latest version on the Chrome web store so for the latest version go to..
