Huh. So, out of curiosity, was Damien meant to be one of the possible romances? Try as I might, I can't seem to trigger a romance with him. Every day since he became available to visit as an activity, I picked it. Heck, I even bought and read that "Charming Devils" book hoping maybe that's what I needed in order to trigger it, but.. nope.
Anyways, I think you've got a solid premise with a lot of potential, but as it stands, it feels a little... lackluster? I felt as though there were a lot of things that could've been explored further. Especially the PC's affinity for magic if we're to believe what the rune storekeeper was saying about the craft being a difficult one to learn. Then there's the aberration itself. Being stalked by it and attacked at your own home was a quality idea, I loved it, but... it's implied heavily that there's some big lore on it/it's creation that isn't presented to the player? I was hoping to find out more about it. Maybe it's just in one of the routes I didn't take? I ended up romancing Matthew.
Speaking of Matthew's route... we never did find out why he stopped going to the Lodge? I mean, I /know/ why, but it would've been a nice touch if, let's say, his mother decided to teach him the proper way to be a hunter rather than letting him go on with the pretenders at the Lodge. If she can't quell his desire to want to protect, she might as well teach him the right way, you know? It also would've been much more satisfying if it was your PC and Matthew that took down the aberration rather than just having his ma teleport(?) in and save the day.
That also ends up bringing me to another point: do the stats even matter? I can't say I really noticed any scenarios where a higher fitness or hunting level got the PC out of a sticky situation (not that there were many to begin with but still) or where the skills "Charm" and "Empathy" actually presented me with a new dialogue choice.
Overall, I think you've got a solid work with some real potential to be something great, especially with some better stat integration.
