I watches the videos of the new KI game, but I think think they the projectiles and particles need some word done still.
Jago's fireball is blandly colored; very opaque for a fire ball.
another is the spark effects, I know this is suppose to not be real, but the particles can't all be the same size. they have the appearance of a Roman candle being lit instead of the molted metal sparks that were introduced in Ki and KI2. those particles need different size and weights!! please.
I haven't seen much of the game, but those are things that really jump for me.
