Great game! After going through the well-presented, non-overwhelming tutorial, I understood the game mechanics well enough to complete the first level... on the second try. I don't know why I was so focused on melee attacks, as the enemy knight could always attack me back. After that, I started using ranged attacks exclusively, and was able to beat every level on the first try. With some rebalancing of the attacks (I found myself using explosion and lightning strike almost exclusively, with the occasional heal, so maybe melee could be buffed a bit), this is a deep and interesting turn-based strategy game that excels at its goal and sets a strong atmosphere in each level. Well done!
