Leaderboards & achievements are live for every game

You can now add a top-10 leaderboard and achievements to any game, HTML5 or editor-built. For an HTML5 game it's two lines — you post a message up to the page: parent.postMessage({ j17score: 1280 }, "*"); parent.postMessage({ j17achievement: "first_win" }, "*"); For an editor game there are two new .j17 verbs that do the same thing in any script effect: score gold achievement "rich" Turn the leaderboard on and define your achievement keys on the game's Manage page first — an achievement only unlocks if the key your game reports matches one you defined. The full write-up is in the developer docs under Scores & achievements, with examples for both. Unlocks and new #1s show up in Community → Activity, and on players' profiles. Curious to see what people wire up.
