Hello, i'm a relatively new runner, though i've been playing for a year now and have gotten decent times on most levels, I downloaded the game on my macbook from this website, I've tried before to figure out how to submit or connect to the website to score my times but lost interest, I got interested again when I got a 8.33 on King of the Mountain, I've dug around the forums for some time but I never found anything. Any help would be nice, thank you for your time.
To submit high scores, you'll need to download PlatinumQuest from the downloads page. Then you can log in with your account and play online to post times on the global scoreboards. You can't do this with regular Marble Blast Gold.
If you recorded .rec files of your runs you can send them in and we'll add them to the leaderboards. In MBG you can do this by typing $doRecordDemo = 1; into the console (press tilde or fn+F10 on mac).
What's easiest though is to just download PQ and play online as that will automatically submit all your times.
Ask RandomityGuy about floating point, bonus points if you tell him "x87".
