Incredible game with small room for improvements
First off I would like to say that I am already addicted to this game and after playing it for half an hour I still can't get past level 3...
Graphics: These were okay, they suited the game, but a bit of colour would be helpful (I've noticed a lot of people wanted colour).
Style: Quite original and kind of creative, I can't really say it's not inventive (I could really, but I would be lying).
Sound: Nice music and explosions, but if you had an option select the music out of three (or more perhaps) soundtracks; you'd be a lot better off. Also, a mute button would be nice.
Violence: I guess the explosions were pretty cool.
Interactivity: It's great that you can control the mouse sensitivity, but you could have difficulty settings for convience (difficulty could change the speed of the missile and the rotation speed of the spinny obstacle things or the likelyhood of the harder ones appearing or something. You could also try using the up and down arrow keys to change the speed...
Humour: A clear lack of it, but it would be very hard to implement it into a game such as this.
Overall: An incredible idea, but could have been a little better really.
Quick Question: How is this a driving game? I thought it was more like an action game...
Anyway good job, great game and good luck.
