Nice idea and great execution!
So many aspects of this game are really good. Visuals are lovely and unique, sounds fits perfectly, gameplay gets you hooked.
Yes, once you see everything, it gets a little repetetive, but I enjoyed all the time spent playing it.
I think I enocuntered one bug - when you have more than 5 units (or combination of units and balista), camera is not following vagon in the traveling segments.
Great job!
