Well except for the exploration, but the makers are right that that can get tedious on a mobile device.
But the battle engine, the story, the artwork, the difficulty curve, are all ... good or better. :) If a person spends time with this RPG, I think it'll be more rewarding than a lot of the shallower experiences out there.
I'm on floor 31 of the Lighthouse of the World. I think I have all the characters now. There are seven whose skills and stats (mostly skills) make them characters I want to take along, but I can only take five. That is good, since I can try a variety of parties.
Some of the artwork is just a little too ... revealing for my tastes, just a little, but never beyond PG-13, as far as I've seen.
