It's sometimes difficult to build upon the simple things in puzzle games. While awkwardly-named, The Book of Wanderer: The Story of Dragons provides a lot of fun, with surprisingly deep gameplay, and enough twists and features to make it stand out.
The Book of Wanderer's theme is quite Medieval, but never gets cloying. From the first strains of the title screen's theme to the in-game background music, everything is atmospheric. Kudos to the composers for this game to write music that repeats, but even after many hours, never gets tiresome. The graphics have a have a high level of polish, and everything seems to have a certain sparkle and sheen.
