Your Pokemon world looks like a Pokemon game on the NDS now. Maybe the author loves NDS Pokemon games so much, he choose the DS-style sprites for everything. More exactly, the Pokemon Black/White styled graphics is used and including some new animated Pokemon.
The design is good also since you will use the Dual-Screen function like a real NDS.
A new function appears for the first time: the PokeMart ATMs. You can deposit, withdraw and check your balance.
The Xtransceiver is here! You can use it to call many different trainers around the region.
New areas to explore and catch Pokemon.
Pokemon are updated to the Gen VI, so the type Fairy cannot be missed.
