Very nicely planned level, and fun to play.
I did the ordinary version and the 3D one. I definitely prefer the ordinary one, though this looked good from a 3D perspective.
With the 3D, the trampoline section was tricky, because in your head you know you have to jump left on the second trampoline, but in fact you have to press the right button, because that's how it would operate in normal view. Quite disorienting.
