Not sure if I'm missing something, other people have said there's a lot of content here, but I can't get past the second level because the dragon doesn't actually land on the moving platform. He just keeps falling into it, and when I try to jump off of it all of the built up gravity gets applied and I zoom down into the lava. I do like some of the stuff that's here though, the 'portal activation' effect of the dragon looks pretty good, and I like how the world goes gray-scale when you turn into a ghost.
