Nice retro asteroids game! Very fun, and the game looks great!
While I was playing, I was thinking that I had to beat the high score of 400 to unlock more games. (I wasn't even close. LOL) But now that I look at your screenshots, I am guessing that the additional games are still in development.
One downside - The game is over pretty fast for me, and it's kind of a lot of work to have to turn on the TV, etc., to replay every time.
