UPDATE Dec 11, 2006: Click this link for Line Rider Tutorials and Videos. Blog's getting a lot of hits after my original post 'Line Rider'. I have been seeing the snowboarder guy on every line I see around me for the past few days. Lying in bed the night before, I couldn't help but wonder how would he ride the diagonal lines the posters on my wall had formed. Nuts!
Anyway, check out the standalone version called Line Rider beta 2. This one has an eraser tool and couple of other helpful features. I must admit I lost interest quite a bit when I had the eraser option available. By the way, who is the real author of this game?
While we're on the subject of flash, and completely un-related to Line Rider, check out this animation created with the Flash interface. It's brilliant work.
