Very well done, from the intro to the 3D world and the controls to shoot at the missiles!
I liked the IR missile lock-on sound being a flight sim fan myself. It took me a moment to understand the way to shoot down the missiles but it works fine and the visuals clearly show what is going on and when.
I was happy to see a 3D entry and thought it nice that there were different difficulty levels available and a very nice title to clearly show the theme of the game.
