Hmmm... need a little more practice, eh...? Mind you, one thing - I still have bugs with the climbing vine-thingees... you have to jump the last bit with one of them in the second level to get through to the floor where it hangs from.
Tends to work best if you only start climbing after the moving camera settles down... if I kept those things in a future project, I guess I'd have to find a better way of controlling a character-following camera - something that doesn't leave things lagging behind it...
