MOON

Moon is a top-down shooter where you have to survive by crafting items.  You start out with nothing on an alien moon.  Then, you have to punch enemies to gain resources such as bones and red jelly.  Use these resources to craft health packs to heal and guns to deal more damage.  How long you survive will depend on your ability to make something starting with nothing.
