That's too bad :( It's definitely a different mechanic. I wish I would have had space for a tutorial level to get players in to the flow of how it works.
Yeah, I'm definitely left with the impression that I've just not grokked something about the game, rather than it being a failing of the game itself. I'm very impressed with the game on a technical level and I'm going to try to play it a bunch more to see if I can crack the code :)
