Well, it is not fantastic, and it can really irritate you at times with bugs, cumbersome controls (partially fixed with a patch) and bad design decisions (like, putting cutscenes IN THE MIDDLE of the action). But there are interesting ideas, it is cool to ride a dragon, the music is good... and "Ravine of No Return" is a MEMORABLE level with its BEAUTIFUL music. There, I said it.

Score: 7.5 (Good!)
