I give you 3 stars just because of the Final Fantasy Tactic sprites, I love them.
The story is nice for now, I hope to see the next chapter.
Now, I see some things that would be cool to have in mind; the times between turns is too longer, when the enemy finished their attack phase, it takes too long to open the actions again, it should be a second or less. The icon for ATTACK could be a dagger, it fits more that way. Enemies should have an HP bar and your attacks value should be visible. Only Phobos and magic attacks are, but not normal attacks.
