One problem, not long enough.
The controls in this game are fantastic, they are all stylus based and quite easy to use once your use to it. You can perform all the standard arwing manuvers such as the loop-de-loop, u-turn and barrel roll. Even just the way you guide yourself in certain directions is quite easy and you won't find yourself reaching the edge of the touch-screen on many occasions.
I live in Australia and have played online play with this game although it took a while to locate a game to join. This is mainly due to time-zones. Although if you lived in the US or Japan you can be assured that many people will be online at a time making it easy to locate friends or random matches. The online play is similar to the missions in single player mode.
The graphics in this game are fantastic, the best I've seen on any DS game to date. Nice crisp graphics allowing you to tell the diffference between arwings. If you simply want a game for its graphics then this is the game for you.
The only letdown is the length, I clocked this game the day I bought it and felt cheated. There are several different level combinations you can go through like most Star Fox games but still doesn't make up for it. The bosses are also too easy meaning you probably won't lose many lives throughout the games. I think games should have bits where you get stuck for a week or so before you can move on, there is no such thing in this game.
Overall a decent game, great graphics and gameplay but couldn't hurt if it was a little longer.
