Thanks for deciding to give the game a second try. Sorry for the issues the first time.
Perspective on character art in general is kinda fucked on the art. Every time I make a new one I try have a bunch of the other portraits pulled up in the same file next to it so I can look at them side by side and make sure everything lines up but it always ends up somewhat messed up. Something I have to work on I guess. I think Duke Circe and Estelle are the worst in terms of looking out of place.
You actually can see Lucerne's buff on her stat page but I get that it may not be that intuitive, you have to hover over the skill icon which should show a popup (though there is an issue where it will go off the side on 4k monitors if that's what you're using). I'll try to make skills more obvious next time.
Sorry about the heal staff bug. Another anon found it the other day and I wasn't able to figure out how it worked until earlier today. I've already fixed it on my end but I wasn't going to release a hotpatch because I want to do some more extensive testing to make sure the fix didn't introduce a new bug.
You should've been able to use the potion, the keyboard controls for the inventory menu where a little janked in the build, sorry about that. As with above I think I've got that fixed but I'm still testing.
For the last mission I agree that the story-gameplay synergy could be a little better. Maybe I can have it so Euphemia is physically blocking off the exit... I'll have to play around with it.
Thanks for the story praise, it's honestly the last thing I was expecting this DD. And spicing up the combat is going to be my next big goal because I feel it is a little plain at the moment.
