Parx (Prototype)

It's a little weird that there's not a unique solution to each level.  At first I noticed this when the last two markers I was placing weren't determined (it could be row A / col B and row C / col D, or row A / col D and row C / col B).  By later levels it meant that I could just click and hope for the best without really having to logic through things, and it would mostly work (which is not a thing that works in a usual Star Battles).
