Good as the first level!
But why are there mixing two music sounds at the start?
The rock's target is:
Map X 8
Map Y 0
Rel. Pos X 7
Rel. Pos Y 3
If this helped...
EDIT: And about the old one: I think, that solving the level's end as the wall of invisible blocks is not natural, normal wall could be better.
And there is wallswim at the bottom second-from-right screen <=> bottom right screen. (some sort of cave entrance)
