The competition on the leaderboards is really heating up and people are performing feats I only dreamed about! Making leaderboards for different aspects of the game has proven worthwhile. Some excel in speed runs while others are better on the longer tracks. Awesome :-D
There has been some good feedback and G+, Facebook, and Twitter, and I have some fixes and tweaks lined up for the next release.
Also - there has been strong demand for an iOS version - so seriously pondering that!
