The game is a lot of fun to play. In contrast to most vertical shooters where the enemies come at you from the top of the screen, you can fly anywhere in ZugyA with 6 degrees of freedom. There are also nice training courses to familiarize you with gameplay mechanics, as well as excellent afterburner effects. Another nice touch I like is how the game forces you to charge your shield before you can use it, so there is a small but important strategic element of deciding whether to use the stored-up plasma energy on the mega-shield, or on your laser. (A bit like Wing Commander, so to speak). You must be careful not to destroy the "headquarter" module too quickly, though, because doing that will destroy all the modules on the level, denying you the chance of collecting bonus items until the next level. So it is always a good idea to make the "headquarter" module the last item on your target list.
On the downside, the gameplay gets a bit repetitive due to the lack of variety in station modules or enemy ships. Every new level looks and plays much like the last one, except for the varying intensity of enemy fire. Still, the novel destroy-the-modules concept and nonstop action will keep the game enjoyable for a long while before you get bored. Highly recommended!
