Icecube Caveman is a game where you roll this 2x1x1 block around the field, trying to get to the destination by rolling this way and that. At the destination, the block needs to be vertical.
There have been many games on the market that has this mechanic so this was nothing new. While the theme was kinda cute, it's not that original. Still, if you like puzzles, this ain't that bad.
