This game is honestly beautiful. For starters, the sound design just sweeps you up, so effortlessly soothing. The simple, pretty graphics and corresponding sounds carry me through each level so nicely. Also, I can't believe I'm saying this, but I must compliment the use of the ads. To ask if you want to see one for an incentive, without being too invasive while asking, was really a nice touch, plus being able to gain something from the ad (an extra shot at the level) is, I think, really a brilliant idea.
This game is the perfect companion to relax for a bit before going to sleep, and I can't help but compare it to the likes of Journey, Flower or Flow, console games that, although this won't hit you on much of an emotional level like those games, this shares a similar unique quality and beauty.
