オラッ掘人 ホレゆけ！ブラジル

When I was a kid growing up in the US, there was a saying that if you dig a hole straight down it would go all the way to China. People in other countries have similar sayings, that you could dig a hole/tunnel to China/Japan/Australia/Brazil/etc. This takes that concept and turns it into a game. Each game lasts about 30 seconds; at the beginning you are given a target country to dig your way to. There's a small arrow (and a flag on the Earth's surface) indicating where you're supposed to go. The larger the country, the most forgiving it is. For small countries, you have to hit the target exactly! When you reach the surface, it plays a little song, shows a picture representing the country and tells what the capital city is. There is a travel log that keeps track of where you've been and when you first arrived there. There are achievements based on reaching certain destinations or completing geographic regions. Your character digs automatically -- there is only a "turn" button. You must manage your oxygen and food levels or else wind up dying and finding yourself in Heaven or Hell... While digging you can find food and oxygen, and there are also some power-ups that will make you dig faster or slower, turn backwards, or kill you. The nearer you get to the Earth's core, the slower you go and faster your life force depletes. A fun, simple, quick game that anyone can play.
