* Add files via upload
Compress images with TinyPNG.
* Update game.dat
Description had "for the Nintendo 3DS' eShop" at the end, which I saw in PR#364 was asked to be removed, so I removed it here in anticipation of such while also adding "role playing" as part of the genre, since the game is an RPG.
