Mary Skelter: Nightmares is a dungeon crawling RPG, so it's pretty different from Idea Factory's most titles, such as Fairy Fencer and Neptunia series. It was launched originally for the PS Vita system, so don't expect the best graphics (as if would matter, as it's anime-style animated). I've played the original version, that explains why I'm reviewing it with less than one hour in-game here. The game is good and very enjoyable. It's not the best DRPG or a game you'll remember for decades, but it's too good for RPG fans to avoid it. Basically, the plot is set in a place called Jail, where you play as Jack and Alice (both inmates) to uncover its mysteries. You'll meet other maidens while you play the game, having more strategy options during battles (obviously). I've played on GOG the prologue and the beginning of the first chapter, and it ran without any problems here, so the port is pretty good. I believe the game won't fail onwards. The gameplay and soundtrack are both fine. The character design and development are great! As I said, not the best, but I love it!! You see, I bought it again just to write it, hahaha... TL;DR: Game is good and the price too, so there's no reason you shouldn't play it. If you don't like DRPG, go for the characters! XD
