Good start, needs tweaks.
You've clearly put a lot of work into the ability animations. The first battle was kind of long since there was no context for plot (if there is a plot to your game, I'll explain in a bit). I wound up selecting the first attack option over and over, and probably would have quit if I didn't see potential (You'll probably lose less patient gamers). Seeing damage numbers would have helped (Woot! I dealt 128 damage!!) since this is supposed to be a Final Fantasy derivative.
At the end of the first battle, the game froze (black screen, music kept playing), so unfortunately you'll probably need to fix it. As such I can't comment too much beyond the first battle.
