I enjoy imaging reasonable scenarios for a game like this. You have a baby crawling, and you are protecting it from all of the evil vermin by shooting DANGEROUSLY CLOSE to it with a rifle. What is the player character doing here? Why are the rats so mad at Boomer? Anyway, enough goofying around.
You need to keep the baby safe from everything by shooting stuff. You shoot clouds to make ice bridges, you shoot birds, rats and cats to protect the precious child, but do NOT shoot the enticing gold nuggets. You actually let the baby get them for some reason. The game has nice graphics, good sound and pretty original shooting action. I give it a win.
