Jamming with changing flying directions to back from forward. Found hard play to fly fast, even at mode 1 or beginner mode (selections: 1-5). A walkthrough video eg. is wished as well, mostly when at the ending section a missile comes straight to and you can not avoid the hit. As far I that knew for now. Big scale scene window does not open. Although that, the game is still were tempting and impressive. Such ease to play by controls. So four stars were given then.
