Platformers are not really my genre, and it showed. I only got as far as the (second?) part with the moving and vanishing platforms. At that point I fell down so many times that I got quite frustrated. Don't know if it's the angle of the jumps, if the platforms disappear too quickly or if I just can't cope with the controls. Probably it's a mixture of all of these. Or it's just because I suck at platform games. Also a very likely option. :)
That being said, the graphics are stunning. I love the character and the environment is just beautiful. The graphics and the wonderful music create a lovely atmosphere. Maybe I'll try it again some other time. :)
