Caveman Runner version 1.2 is now available as a free update to all of our runners out there! Everyone loved the hearts that replaced the steaks temporarily in the Valentines day version, so for this second free update to Caveman Runner the steaks are back but some hearts remain sprinkled in. They appear randomly and float about, adding a new moving target to the mix. Keep track of how many hearts you have collected on your phone cumulatively between games! When you get to 50 you will unlock the Sprint bonus.
