Ok, I give up on the hard run on first playthrough lol. Maybe it's doable if you start supper optimally, but there just doesn't seem to be enough divisions to defend against so many enemies that just run past at the start. I made 2 strong divisions as a priority and a third decent one after. MC's team attacks whatever is the most troublesome. The other strong team was guarding the entrance... but they can only fight 1 battle per turn, and everything just runs past or starts breaking buildings, so you really gonna need a decent amount of usable divisions. The starting division of shit tier units just won't do anything on hard.
Another mistake was focusing mostly on resource production buildings. I was enticed by the permanent boosts when you win battles, and I kinda spammed some of these resource buildings which don't help defend at all.
If I start over on hard, maybe I can get something going, but I think I'll just do normal first. Normal --> Very Hard was my route on Hollow, so I'll probably do that again.
