MUSIC
I enjoyed the demo, but you need more musical variation. I would get bored and quit after the first three levels if it just played the same loop over and over again like it did here. You need different music for when you're telling them what to do, for when your lining up your attacks in battle, for when you're actually in battle; and you need sound effects for all the attacks, and conjuring and whatnot.
I look forward to the full version, with a full soundtrack hopefully.
