Touch Arcade: After a few hours of Oneclick's Angel Salvation [$0.99], you're likely to have developed Tetris Syndrome: colored gems, healing crosses, and devilish earth-tyrants will dominate your thoughts. It's turbo-charged high fantasy aesthetic notwithstanding, Angel Salvation begins zen-like, and your eyes may begin to glaze over as your fingers move about the screen, lazily flicking gems around, making matches and raining hellfire on your enemies.
148apps: Barring a few foibles (and an internet requirement), Angel Salvation is actually a really cool match 3 RPG.
