I think they chose to keep the same feeling and same issues.
I never had any issues myself with all the game mechanics or graphics, but some users seems to not be happy how the original was or worked. I never had issues with magic, battle system (time charge) or anything else. everything was well thought and easy to play to me.
The graphics are identical, NPC, sprites and tiles placement, etc.
it helps keeping the Snes nostalgic feeling, but at the same time why not play Snes version instead if it's a clone? people who never played it can play this version and will find the exact same game we played 20 years ago.
they said the music was redone, but I didn't heard differently. Maybe it's now a real "music" and not sampled instruments played in realtime which cutoff when too much sound effect is played at the same time
it had its charm, the Snes had limited channels for sounds, and some music instrument were mute to hear sound effects (sword slash, monster cry, etc.)
the only thing annoying me is the minimap with the SNES graphics.
I just find it strange to have a mini map on the corner, why would people need a minimap ? people get lost on Snes version ? "you are here ... wait, you know where you are because the map is the same thing than what you are looking on screen"
the minimap is not far enough to be interesting.
it explains why it's so similar graphically, and not a real remake done differently. the world is just transposed with 3D graphics. when you move you see the position on the Snes map is moving too. both matches, so I guess there won't be different maps.
