I absolutely adore this game, but imo it's a terrible candidate for a remaster. The graphics were already stylized so I doubt a graphics update would make much difference. It's a puzzle game so the replayability is already low. And I can't imagine that developer commentary get people excited about buying the game again.
I wish this was successful, but I can see why this went sideways.
Which level(s) will you be playing at? I personally prefer the Barbarian class's flavor over the Fighter, but depending on level, you'll get more attacks and ASIs as a Fighter.
Overall, I'd say a Champion Fighter would be more straightforward, but a Berserker Barbarian would be more fun to play.
