Interesting game. I like the concept, but some kind of tutorial or an explanation of the battle system would be useful. I was very confused while playing^^" A visual indicator when your move is out of range would be helpful too. AdvAnce Wars for example uses different colors, which is obviously not an option here, but something like a cross when the cursor is out of range would help.
I really like the atmosphere that you created. I hope that you'll work on this game after the jam, because I would like to see more of it^^
