Well paced
I thought this had some good graphics in it, but the downside was that it was actually pretty hard to understand. At first, I did not look at the instructions and thought that I lost my killing the caveman! What is kind of annoying is that you have to start right at the beginning after losing. As there are a lot of levels, that can get pretty frustrating. I did manage to get really far, and only failed because I wanted to get the medal of hitting the bird! As I care little for cavemen, I had no problem crushing them.
The music was pretty appropriate and I am now starting to notice that all of these games are ice themed. Man, I should have really caught onto that earlier. This is the kind of game that takes patience and unless you are skilled at timing, you should probably spend too much time on it. There could have been some more detail in the cave, but it would have probably not mattered. Next time, yes, you should have allowed us to start on the same level.
