Thanks, glad you enjoyed it!
And great to hear you enjoyed the tutorial. That's the hard part of being a solo-developer, you always understand your own game inside-and-out. A friend of mine didn't understood the concept, so I created the tutorial (took me quiet some time to make it as thorough as it is now). And eventually I was afraid people would bail during the tutorial, since it was lots of text.
So thanks for the comment!
