I only played it a bit, but it seems interesting enough that I may return to it this weekend. Even with the "hint" in the other comment about the movement, it was still confusing the first time i saw it.
Well, cool. I'd appreciate any feedback. Almost everyone has commented (mostly negatively) on the movement, but I do think people get it after a few seconds. If I hadn't used this movement, you would always know which way is which easily. Hard to simulate getting lost/going in circles in the freezing cold without that.
