Got it. I should probably change that, then- Attack should honestly be the default, kinda like it is in Fire Emblem, since then you know X amount of inputs means Y just through muscle memory. I'll see if I can get that by next patch!
I'll definitely add a training "Skirmish" map set with that patch as well. You won't progress toward endgame, but you'll be able to fight a sizeable amount of Gremlins and get some XP so you don't get softlocked. To bring back the Fire Emblem comparison, it'll kinda be like the Tower of Valni in Sacred Stones or the map skirmishes in Awakening- the option to grind is there, but not necessarily required.
