The game looks very interesting, and production quality seems high. http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301461765&mt=8 The price tag of $4.99 is slowing me down (though they say this is a 'limited time low price' ... we've heard that before). Anyone tried it? Impressions? Is it a brain game? ... dexterity game? ... or both.
