And, of course, a gameplay screenshot:

Nuclear War. Truly, the end has come. Wait, is that a cereal box?
You dig a fallout shelter, then hoard supplies in it. The ultimate goal is to extend your shelter all the way to the cavern below, and re-unite with the rest of humanity. If you make it there you even get to submit your score (a composite of how much stuff you’ve gathered) to the leaderboards!
Download Shelter From the Rain for Windows, or get the Python+PyGame sources (for Linux).
