Hi, thanks for purchasing.
the bar with time and 3 hammers are the hammer time life span, if failure or not reach minimum point, you lost 1 hammer life.
the hammer powers are level 1, 2, & 3.
for example level 1 can beat normal moles. but need to hit more for greater moles... and so on level 2 or level 3..
you can improved it what you like.
