title: Creating and saving maps with tiles in XNA
body: <p>I'm trying to make a "dungeon crawler" type game demo, and this is my first time really making anything beyond Pong &amp; Pac-Man clones. My big hang up right now is creating the actual level. I've gone through a tutorial on how to draw tiles onto the screen, but I can't find anything about where to go from there.</p>
  
  <p>How do I go from one screen to making a larger dungeon? Any help is appreciated.</p>
