Since I’m also adding a hard mode, I might go back and make certain levels easier in order to make the difficult level more uniform between normal and hard. I’ve already gone through and changed all of the ambush spawns (reinforcements on the enemy turn) into normal spawns for normal mode, so hopefully that also helps alleviate the difficulty somewhat.
My basic philosophy is: if it can’t fit into one patch, it hasn’t been implemented properly. I might tie it to one of the early achievements and implement the 2x EXP mode to make things easier for players.
