It's an actual, non-gacha RPG on mobile: not an especially good one, but it doesn't have much competition. It plays fine and looks good if you can get past the truly heinous number of enemy palette swaps. The writing is bad—it's like a straw JRPG imagined by someone unfamiliar with the genre given physical form—but aside from that, it's totally inoffensive.

There's zero reason to play this on console or PC, where plenty of other, better RPGs are available. Frankly, even on mobile, you're probably better off going through Square Enix's library of ports.

Side note: After Hearts, Kemco switched from hand-drawn animated sprites to tweened ones, which look like absolute shit.
