Thanks for the feedback. I have been getting some comments from friends as well about the first couple of levels being a little mechanically tough and not directly intuitive. In Alpha 6, I made some changes to the help tips displayed at the bottom of the screen to be more helpful. So they no longer just tell you what to do but also offer some tips and tricks to clearing some levels.
Tip: Hold S until you reach a maximum height and then jump at your highest point.
Glad you enjoyed.
