Pretty good game so far. Not much to do, but for a demo, it's okay.
It does look like some scenes are using AI but it's not very noticeable. The combat becomes very easy the moment you get the Greatsword.(you just do: 3 Decapitate, 1 chop, end of round ability. next turn you just do the tempest slash and it kills all enemies because of 10 might stacks)
So far I've managed to get 3 memory crystals, and it looks like you can't get more (or I just couldn't find them).
Overall there are 2 scenes with the MC, 2 at the training ground and 1 with the shop owner. There are also small scenes of harassment, again with the shopkeeper, the guild guy, and the kid from the church. (I'm pretty sure there's supposed to be a scene OUTSIDE the shop when you get the repeatable delivery quest, but it's either not in the demo or I just didn't have the patience.)
Also, choosing to ignore the sister's request seems to give one scene with the shopkeeper and then nothing.
If you don't ignore her you just basically get drained of stamina and gain nothing.
In conclusion, I think it's worth adding this to your watchlist and waiting for the full release.
