Gate of Memories was finished ages ago, there's even a 2nd game released about Nameless (the edgy one armed guy) with slightly different combat mechanics since he doesn't have a teammate to do switching combos with. They're both extremely good games, but they're also definitely very janky and rough looking. Very reminiscent of the experimental action game era of the 2000's, like Nier Replicant for example.

Abyss of Song or some title like that is their upcoming game in the same universe that you might be thinking of, the development on that was basically halted entirely due to personal reasons of one developer so the rest started work on this remaster as I understand it. As for sales, no idea but it was definitely decent for an indie title.
