For a fangame this is excellent and deserves mad credit. That said, and since others have already showered praise on the good aspects, I'll be very blunt with my impressions: for the standards of the SNES era this isn't a very good rpg. It does not come close to Lufia II.
I found it to be poorly balanced, full of tedious mechanics, and often cringeworthy. There's a ton of issues both minor and major, and way too much focus on shallow minigames. It would have been a much better game if the basics were stronger.
However, as a fan of the saga, it won me over in the end. It gave me closure I didn't know I needed, and many scenes have genuinely great writing.
It is self-evidently a labor of love, and that passion and effort shines through all the jank. Anyone nostalgic for the Lufia saga should play it.
Notes: I played version 1.65(fixed), full completion over 40+ hours
