One of the best games I've played for the eye candy of the environment alone.
While there's problems with the game dragging on through levels, boss fights and some graphical quality inconsistencies it is a beautiful and fascinating old school platformer. It's a shame that it has EAitus and a lot of content was cut and seems to have required a few more months to fix it.
Oh, and what I love most, great fanart:
