Simple fun concept, but needs polish – RunStickRun 2 Review

It's a simple fun game that's very addictive. I would like to see some improvements. First, I wish the running figure would be animated smoother. He maybe has four frames of animation. Also, my iPhone 4 doesn't seem to accurately detect which color direction I'm swiping. Perhaps an option for buttons? Lastly, I wish there were checkpoints. I hate starting over from the beginning every time I die.
