Cool Game! I think there's so much depth to your guys' combat system and I would love to see a full game using the maze building mechanic. However, there is little incentive to not just keep going back and forth over the same few tiles, maybe the number should reduce by one every time you cross that tile. Apart from that, the art is great, maybe could have used a few more animations.
Overall, I would love to see this concept expanded in the future, maybe polish it a little more but great job and keep up the good work!
