If at first you don't succeed, You-Tube it.

I manged to get through 1 level today, after 5 play-throughs...

the main problem was that the 5th level starts off with a big open area that you use the flying cloud with for the first time. Spread around this area is dozens of orbs to collect and there is no way to tell if you got all of them until you finish the level, and then you just get a percentage. So I finished the level with about 96 %, so I red did it and found 4 or 5 more orbs that I missed. Then i was 98% so I went at it again and looked all over the rest of the level to see if I missed any orbs there, which I hadn't. So then I look on YouTube for a video with the location of all the orbs, and I find 3 more. So I finish the level and now it says 99%. It then took me 2 more tries to finally find the 1 orb that I kept over looking!

Also it's odd that the only pre-rendered cut scene that I have noticed so far looks far worse than the actual in game graphics.
