Please, please, please add a speed-up function, yes. Battles feel very slow when you already know all the moves you’re going to make (an “AHA!” or “EUREKA!” moment where you systematically move your troops in a way you know will secure your win, etc). Then you have to wait for the enemy’s turn and it seems to take ages because you’re so excited to get to the next part…
Yeah, I’d definitely love a combat speed option. And I’d also love an overworld map speed slider, too. Maybe a couple of + / – buttons a la speedup / slowdown options from The Sims, for instance. Press one way or the other for speed adjustment, with a “normal” speed button in the middle (0 being normal, -1 and onward being slower, +1 and onward being faster).
