In the demo, only one character is under your control in combat. The issue is that you will gain 1 point of time guage before you can choose Attack or Black magic (which you select makes no difference, anyway since you can combine skills from both in one combo o_0), choose your target, and choose a 1 point action. Choosing two actions will be close to the time to get 2 points of time; you have plenty of time to choose 3. Instead of letting you plan the next attack while the current one is in progress, you have to wait; moreover, the UI sits there and lets you choose attacks and stuff then discards it when the current attack completes.
