Glad you liked it. I guess our tutorial level wasn't too clear on how battles work. You may have come across a bug in level 3 or so to where you cannot continue. We apologize as we couldn't fix it in time.
I've read the comment on the dude who played before me so I stopped after level 2. But yea, I would be fuming if I just cannot find the last one as I was always garbage at navigating mazes.
