Jukebeat is a mobile adaptation of Konami's touchscreen arcade game Jubeat, in which you tap one of sixteen squares on a giant touch screen in time with the music. The iPhone version works the same way, except with sixteen squares on your little screen instead of a giant space cube.
It's pretty rudimentary in theory; you just tap squares as they light up, to the tune of the music. Except you get very little warning before you're supposed to tap, and you're often asked to tap two or four squares simultaneously. The only way to avoid failure is to practice, recognizing the patterns and memorizing as much as you can. And even that's not a guaranteed method for avoiding failure, if my own history is any indication.
The free app comes pre-loaded with three Konami remixes -- one each from Contra, Frogger, and Lethal Enforcers (!) A few other song packs are available for $3.99 each, but ... I'm still working on these. I haven't even ventured into the harder difficulty settings.
Jukebeat is available from the iOS App Store for free as a universal App. We're always looking for new distractions. Want to submit your game for Portabliss consideration? You can reach us at portabliss aat joystiq dawt com.
