I played this a few weeks ago, and really enjoyed it.

Here's their site: http://doomanddestiny.com/

It's a fun little RPG, I played it on iPad, and it fully amused me for around 20 hours (not bad for 1$).

Turn based combat, a pretty funny story line, and a bunch of optional side quests, after you've completed the main goal of the game.

There's throwbacks to Final Fantasy, D&D, Pokemon and a slew of other things.

Oh yeah, and the final optional boss fight - against the 'Flying Spaghetti Monster'
