Wow, such a great system you have established! It lacks some stuff like sounds, music, a less grey interface and a clearer tutorial imo. But your board, your little drawings of runes & monsters and your gameplay really are good! I love games like Puzzle Quest or Gyromancer, and I could definitely see some potential here, with some story telling and a worldmap with quests (even linear).
Develop a little more the strategic aspect (with visual strentghs and weaknesses on the board maybe) and you could obtain a nice little Puzzle-RPG :) Well done!
(and sorry if it sounded a little harsh, I speak as if it was a finished game rather than a game jam one)
