So incredibly pure and good-- it's easy to miss some of the incredible effort put into the game. The music is sweet without being obnoxious or repetitious (though it repeats), and the small details in the world are fantastic. Each room in the game is unique and has a lovely texture to it. The whole game world feels lived in, with small details to coax the viewer's curiosity to the world's past without making it the focus.
My favorite part is seeing the mech on the hillside in the background on the cliff. a+
