PetWings is a cool vertical shooter similar to Galaxian, except with crisper graphics and an awesome anime style which is reminiscent of the famous Twinbee series on the console. The basic premise is simple: shoot everything in sight. When you shoot an enemy ship/monster, it drops a potion for you to collect. After sixty potions, you will get a power-up. The game is similar to Defender in that you will usually be faced with rows of monsters that move in tandem, although the game is arguably much more difficult: the front rows fly, and the back row lurks behind shooting at you. The registered version has 53 huge levels, five bosses, and six levels of weapon power-ups. The shareware version already has sixteen levels, but for only $5, you can't go wrong with the registered version. Definitely one of the best shooters I have seen in quite some time – two thumbs up!
