Improved. – Alpha Zone Review

Further development has given us a more playable experience overall. GameCenter is now included and the difficulty balance feels more even. The collision detection is still the major issue here. You WILL collide with things your ship isn't touching and you may not even realize it. Hitting an obstacle elicits an imperceptible digital fart and causes your ship to flash briefly, which is hard to notice when looking ahead at speed. There are a few bugs regarding powerups that move when they shouldn't. This title would be easier to recommend with a bit of additional polish and perhaps a more exciting scoring system.
