I was have a bunch of fun with this, and then walked backwards out a window or something and ended up in a 2x1 area with absolutely no where to go it seemed :(. It was right across from where, I think, I was about to get a penguin-like guardian. Not sure if I missed something (in hindsight, perhaps something I needed to click on? I was using the controller up until then...). The guardian hex grid was really cool, I enjoyed playing with different options, and really nice that I got immediate feedback on what kind of attacks everyone had (as I was unclear if "X damage" meant base damage or no damage ^_^).

Eugh, yeah, sorry; now that you mention that I can think of exactly where that is. That 2x1 is part of a later section of the level that was never finished; I must have forgotten to put in a thin wall on the floor above where the window is, so it's possible to fall out into it. My bad entirely!
Thanks for the play and the helpful feedback, and hope the bug didn't spoil the experience too much!
