Graphics are great, creates a really cool atmosphere. Though its a prototype, the base concept is appealing; grappling to go farther down is a neat twist and the controls made it pretty satisfying to build up speed. Set my mark at making it to 100, but I topped out at around 85 (damn Paul kept slowing me down, er, I guess slowing me up). Cool to see that even without a set objective there's joy to be had here.
