Just noticed that spokko's latest Tiki Totem (Lavalanche) game is currently FREE on iTunes also their fully paid-for version (Tiki Totem Premium) is also FREE. Geofighter - Light Wars is FREE. Grab them whilst you can all are excellent apps for the iPhone and still being played on my own iPhone :)
Also worth noting that their other free offerings: Tiki Totems 2 Valentine & Tiki Totems 2 Builder are both very good additions to anyone's iPhone, iPod Touch or iPad
Sorry in a rush will add more info shortly!
