Grind
It's a fun little game, if not the most blazingly original, and personally I don't even mind the limited turns. It's pretty well implemented and I like how the maps work, especially the sanctuaries and so on.
However, for a CASUAL game with very limited free turns, the difficulty curve between levels seems very steep.
For example, when going down to L1 of the sewers, only my magic user did any decent damage against some of the enemies because of their elemental weaknesses. This makes perfect sense. However, although he was in the back, and had as much armour and other protection as I could throw on him, any and all enemies could attack him and wipe him out, no contest. The enemies on the level just before that were, by contrast, pathetically easy and gave almost no exp and gold. And with limited turns, there is just no way I am going to spend time grinding on a casual game.
