The original took 5 years to make, and as far as I'm concerned the longer they spend on the sequel the less likely it is to be a soulless rehash of the first one.

She's featured prominently in the preview art, so, probably? It seems like they're putting more thought into the backstory this time instead of making it up as they go along, so there's surely going to be some explanation for it. Hopefully the explanation isn't that Lemeza failed to destroy her soul or something along those lines.

A large amount of patience and a small amount of masochism. Keep in mind that a blind first playthrough could take you 40-60 hours, so it's a pretty fucking big game relative to other games in the "genre". You may have been making progress at a reasonable pace even when it didn't feel like you were. Either way it's a niche interest, they never expected the game to catch on as much as it did so you shouldn't worry if it doesn't appeal to you, it doesn't appeal to a lot of people.
If you ever feel compelled to go back and try it again sometime I'd recommend playing the original, in my opinion it's a little easier than the remake and it's a more purist MSX-style experience as well.
