title: HTML5 canvas collision-detection
body: <p>Can anyone please help me out with a small test game I'm creating. I'm basically creating this game to learn a few things about HTML5 and so far it's all been good. I've been able to create a canvas with a air balloon that can fly and drops to the bottom when it's not. Now I want the air balloon to be able to stop on another block image, which I've called "level1". If someone could perhaps have a <a href="http://tehwebz.com/html5/game.php" rel="nofollow">look at it</a> and view the source and suggest how I would do this, I would appreciate it. Thanks again. :)</p>
  
  <p>EDIT: Or perhaps this isn't the most efficient way to create a level. If it isn't then please say. :)</p>
