Not sure why this game hasn't gotten more attention. I've only managed to put an hour into the game, but so far it plays like a full-fledged SRPG -- for some reason it reminds me of Disgaea, but without the juvenile humor. It has a story (which is a both familiar and a bit disjointed, but not terrible), NPCs, cut scenes, etc, as well as a fair amount of depth both in the combat mechanics and character leveling. Visually it's pretty impressive for an indie game, with colorful environments and decent character modeling and animation -- it looks like a 3DS game. On an iPhone 5 it moves fast, especially in the enemy phases. Scrolling and rotation are pretty much flawless.
Oh, and even though the game is free to download, the two IAPs are one-time-only: to unlock the full game and to get a "leveling" item that makes the game easier for casual players.
I would definitely recommend the free download, at least.
