Indeed I have played a bit of it, I feel though that it is a remnant of larger plans which either due to time or laziness never properly panned out. My thoughts is that this was supposed to be on the 3DS possibly in the episodic format that was used with the original Wii release, but for some reason Nintendo didn't want the idea or partially through development Square-Enix decided that it would be mobile only to go with the new revamped FFIV 3D for the Mobile already out at the time.
It's a distinct possibility that FFIV-3D did really well on the mobile market so they thought to follow up that success and it does seem to have worked. From reviews I've read people seem more satisfied with TAY in 3D than they did with base TAY (Despite it actually losing some content). It is essentially the same game, still the same flawed battle system of FFIV where every normal foe has far too little HP, any improvements from the DS game such as Augments or revamped enemies is completely missing and the only changes are some changes to chests that now contain Adamantite instead of finding it in the Challenge Dungeon final chests in a random fashion.
This is why I feel there was laziness involved, a proper port of the game to the 3D format would have followed in suit with its predecessor, if nothing else they could have at least easily taken the FFIV DS enemies and worked with that, but no.
That said the presentation is much better. Some specific cutscenes have actual emotions, camera angles are put to fantastic and expressions put on the character's faces and the 3D actually looks really good. All in all it is still a solid package, yes it's flawed like the original FFIV, and you can't expect much different going into it (if you've played before which you have not. So it will be a brand new and possibly more well-crafted expereience for you), but it's still a worthy venture and a good pickup for the mobile.
