Which aspect that not relate to bug issue and unfinish gameplay? Bc the only thing I can see is maybe artstyle, Ui friendlier. Otherwise of course you feel like that bc this thing still in WIP(Not being a dick here :] )
There's one slight, um, maybe not a problem, but timeline... inconsistency?
The first game was in development for 2 years (plus the final patch that was basically done by someone else a year or two later).
This game has been in development for 5 years already and there's seemingly no end in sight. You'd think that the dev would've figured out most of the design problems by the time they went about doing what's essentially a remake and streamline the development as a matter-of-fact and yet it's still missing things that should obviously be there and already were in the first game.
So yeah, I guess, it's mostly about unfinished gameplay.
No idea about a "friendlier" UI, though, it took me way too long to figure out how to go to the town to be considered "friendly". Maybe you meant to say "easier on the eyes"? But even that is wrong, the first game's UI was easier to figure out, navigate and looked better.
Not to mention clear inconsistency in design, for example, most windows/screens have an [X] in top right corner, but Work tab has a huge "BACK" button in the middle at the bottom for no apparent reason. Also I'm pretty sure one of the main menus outright doesn't have any button to back out of it and you have to ESC out of it.
