A sequel to a lesser-known original, Pwong 2 is like the hyperactive biker outcast stepchild of its Pong parents. This game offers some serious sensory overload. The basic principle of Pong is still there; two opposing paddles whacking a ball back and forth, hoping to score by shooting it past your opponent. The first difference is that Pwong 2 has a vertical layout, rather than the more traditional sideways playing field. Everything begins deceptively normal and steady, with just a single ball lazily knocking back and forth between you and your computer opponent. Use your mouse to slide your paddle (on the bottom) from side to side.
All of the sudden, a few more balls enter the mix. It's okay though; you're doing good... just a few balls, right? No big deal, just keep moving back and for—"Arrrgh!!! What the #^@&? Too many balls! They're everywhere! Game over man, game over!"
As if a dozen or so weren't enough already, the screen will eventually become filled with balls flying left and right, up and down. The more balls in play, the less they'll count against your score if you lose them. So at least there's that. You also have a few tricks up your sleeve, like the ability to launch a "ghost paddle" up in the air above you, used to preemptively catch incoming balls without actually being in that spot by the time they get there. This ability is fueled by ammo that you can snag by collecting the bigger, glowing orbs that occasionally descend. Just click the left mouse button to fire it.
You'll also see a few other nice power-ups drop from time to time, like paddle extenders, slow-motion and "sticky" paddles. You can also upgrade your paddle between matches, spending the points you earn on three things: extending your paddle, making your paddle's "curve" more extreme and the length of which power-ups will last (or the frequency in which they drop—it's not specified).
There are several different game modes beyond just Easy, Medium and Hard; the Extreme and Insane modes give you less time and more of a challenge. There's even a two-player mode that you can play with a friend, using both the arrow keys and [A] and [D] keys. An achievement system is included, albeit sparse.
Analysis: By nature, there's just not too much more to the game than what's immediately obvious, so it can get a bit repetitive after awhile. The glow-trail graphics are a neat effect, but could also be an annoyance issue with some people (not to mention the high-frequency, trance soundtrack if you're not into that sorta thing). You can mute the game with [M], pause with [P] and reset with [R]. When it comes to gameplay, there really isn't that much to criticize since you're just moving a paddle back and forth. I suppose gamers with a high-end, 2000 dpi mouse may have a slight advantage over those with a junker, but I can't imagine it would be that substantial.
It's a casual action game through and through, shiny enough to capture your attention for 20 minutes at a time. Just don't expect much in the way of replay value after you've completed all the difficulty modes and achievements.
