The actual game is great, I love the swinging mechanic and box2D runs great for what this is.
However, uploading the tutorial as it's own game, seriously? It's 500kb, you have a link on the menu of the actual game, there is no excuse what so ever to have this be it's own swf, it's got to be for more CTR and cash, if you have a legit reason to do so, please enlighten me. I know for a fact that a game going from 6.9MB to 7.5MB is not an issue, you have room for the button to the tutorial in the main game (because it's there, and opens up this page), so why? I just played it, and it's a single level, one screen. You already had the main menu in the original game, all you needed to do was add this tutorial map into the main game, and you would have been set. Please enlighten me, I'd love to be wrong about this, unfortunately I'm very certain I'm not, and this part of the game gets a 0 from me. To be fair, I did give the actual game a 4, it's good stuff.
