Being able to actually control the camera makes a huge difference.
The last bone at the top took me 3 attempts.
Most of my time was spent on the very first jump onto the tower (the bit you need to jump of the wall to reach the small platform). I still do not feel confident about making that jump.
I noticed your moving platforms are not linear, which might require some getting used to. One big improvement I think could be adding a fake shadow under Mel, so players know where she is about to land while she is midair (like in classic crash bandicoot games for example)
