I just realized I never gave this a rating despite really enjoying it. The art is great (exactly what you see by the screenshots) though definitely inconsistent, some scenes have her with a bust probably2-3x her normal size (though it's never really a huge issue, never really took me out of a scene). There are puzzles, but the only difficult ones just have some extra goodies in chests, it's definitely not necessary to get them. There might be a bit of a grind at the end as the final boss is a bit of a step up from previous bosses, but it shouldn't be a huge issue as gaining xp doesn't take too long.
If you're having trouble with this, there's an armor that raises your mp pool, just combine that with the spell that increases damage dealt with your mp pool and you can one shot most enemies. Alternatively, you can grind crystals in one of the areas by leaving the area and coming back (there's a spawn point right beside the entrance to that section of the map so it's like 2 seconds to get a crystal). Sell the crystals and buy the mp dessert in the initial area to raise your mp pool relatively quickly. That method is rather boring, but gives money very quickly as each crystal is worth 500. Once you get some extra points in mp, you can kill the final boss much quicker too.
