That's almost a full game ;) Lovely art-style and music + interesting gameplay.
On my first session, I've just played without strategy, until I lost a combat and the game (the first with 5 guys with a knight, with the big difficulty gap !). I 'll give a retry by carefully managing the items and the strategy :D
If the plan is to make a casual game, then I think that there are too many info at the beginning, even if there is a good tutorial. I havn't paid attention to the "affinities" system, neither RPG elements, because it looked overwhelming and there is a lot to learn in few minutes. (As a game-dev myself, it is very difficult to make a good impression on someone who is playing the game for the first time.) Once you get used to the game, then almost everything makes sense.
