Cool little game. I like the art style for the world, but it seems to be a little mismatched with your character, enemy images and music. You have a kinda gritty theme going and the cutesy world is a bit strange.
The combat is nice and straightforward. When a character uses a turn, it took me a while to realize the portrait turns gray - it's very subtle, I would make the gray nearly black to contrast.
The grid system kept throwing me off, it felt like you should be moving a lot more each square - I don't know if you really gain much by having it so small.
I like that you have minigames.
Nice work.
