Gave this a quick playthrough, fun times. I really enjoyed the management elements and the relatively large impact they had on the RPG gameplay in terms of ability gating etc, and the RPG combat has an interesting balance between being 'able to predict what will happen next' versus 'not sure how many attacks etc'. Pacting an enemy seemed nearly impossible and even on normal it took a few goes to figure out how to go about taking down some of them.
My feeling was despite the various choices I couldn't tell how much was going on under the hood in terms of changing of the story, or even if there was any (besides getting a hug CG or a kiss CG at the end), though it's more excusable in a short story form like this. I suppose the stat raising will be more Fire Emblem 3H, with a full cast and crew, in the full game?
I really liked the two leads, though not having any other character portraits for the students was a bit jarring, and I feel like there were timing elements with delivery (very click-click-click with no dramatic impact caused by pauses, screenshake, etc). But it was a good run nonetheless.
