got, it. now I am stuck in about the same area again.
This time I already got the white wings and currently have 0 of 5 items.
Not sure if there was some new power at the last levelup that I jsut missed.
but I feel down that hole at the bottom right , cant climb back out, cant go further down due to vertical vines.
and again climbing up the path on the right (that leads to the ceil walking part mentioned before) is impossible cause theguy now is too big to climb it :-/
