Thanks for the feedback!
In cemetery sphere (the blue one) you're supposed to knock over headstones (by just walking into them). Apparently, this isn't very obvious (and I guess trial and error method didn't work in a reasonable time frame), I'll think how to improve visibility of the required actions.
About platforming difficulty: it's interesting because I was afraid it would be too easy. Overall, I guess, it's a good thing cause there is some learning curve with the control mechanics and by knowing right tricks you could access any sphere in seconds.
Finding a path to the spheres is part of a gameplay. As for scaling controls, yes — It's not particularly polished, I am still working on that, but again — thanks for pointing it out.
