I give this 5 stars. Why? Because it seems like an exemplary system before it's even in the Alpha stages! I like how tides are timed instead of just being "you, make a move. Now you make a move," and so on. And during tides, you can do just about anything; whether it be waiting for your gauge to fill its tiers in order for you to use stronger attacks, or going on the immediate offensive and attacking with both of your level 1 moves at once. Speaking of that, the fact that you can make both of your characters attack simultaneously, even keep using just one while the other is preparing for a stronger offense, is a very good element of this system.
Keep up the good work! I can't wait for a game with this system utilized in it.
