Ah, the simplest ideas are often the best, aren't they? And games don't get much simpler than Pang!
Run around shooting bouncing balls with a bizarre harpoon style gun. When you hit the bals, they divide into two smaller balls, one of which keeps going in the same direction, and one which goes in the opposite direction. Shoot too many big balls and your level is suddenly full of small bouncing balls which are incredibly difficult to avoid. Touch one and you're dead! But shoot the balls with systematic cunning, and you'll survive to the next level. The levels are fiendishly designed with blocks to make the balls bounce in unpredictable fashions, and some of these blocks can be destroyed, creating an almost puzzle-like gameplay.
Pick ups such as double-fire, sticky fire, time slow-down/freeze and even guns can be used to help you solve certain levels.
This CD gathers all three of the Pang games into one disk. The first is, unsurprisingly, the most basic. The second and third simply add not only better graphics and game complexity to the proven formula, tey also add Panic mode, which is an ideal training method for the objective based main game. The power of the playstation is hardly showcased by this game, the NES or MegaDrive could manage these games with ease... but it's about gameplay not hardware power.
Pang is one of those "just one more go'"games that you think you've been playing for twenty minutes, but then you look at the clock and realise hours have flown by. Highly recommended.
