Psychosomnium
More of an art than game and that's why I liked it sooo much :).
Graphics: I just love a pixel-art games - of course when it's done well. Detailed and smooth animations, simple and original design of characters, same goes for map, obstacles and backgroud. There's one word describing every art aspect of your game - harmony.
Music/Voices: Also here I do not have a bad word to say. Music nor voices didn't make my ears hurt - they're just brillantly composing with rest.
Game: Short and simple story - nothing more to add, everything sticks together well. Puzzles are a nice touch, I really liked them. They are not complex, but not easy enough to solve them by first approach (as for me).
Little, but well designed game, without any unnecessary filler-kind-crap. Good from the begining, till the very end. Great job :)!
