I agree about the previewed characters bodies. I mean, they all look pretty good, and the faux-pixel style is way above the generic dead stares of the plastic looking AI zombies that make up 99% of AI art. Wish there was at least a little bit of diversity. I get wanting to age up a character like Myrrh, but I would still much like to see some girls that have something at least a little more petite. If the game even gets that far. Fingers crossed, but its a Fire Emblem porn game. Also, having Ephriam, or introducing a Mark-analogous character to actually be fucking the girls, feels like a much better choice then what is in this... proof-of-concept. Seems a shame to leave it to the villains. Lyon would make a decent choice too, but you'd have to do some real fenagling with the plot to have him around enough to have a decent amount of sex.
Also, really weird that its made using RPG Maker, when SRPG Studio also exists and is actually designed to make tactical RPGs. I know RPGM is braindead easy to make things with, and SRPGS actually requires a bit more flexing to get its work done, but still. I can only hope that the dev either looks into finding a tactical RPG plugin (I know they are out there), or switches to SRPGS. Because this feels kinda low effort, even for being, self-admitted, two days of work. The potions aren't even called vulneraries. The potential is there, and I desperately want it to be the best version of itself, but the creator has their work cut out for them.
