it's not a memory leak, btw.. memory allocation doesn't appear to go much about 512m .. it's the interval or update work that's being done... it's being called waaaaay to frequently [not a unity dev even remotely, so i'm sure i'm using the wrong terminology].

It's finally solved. In editor I have stable 30FPS(lol) with continuously spawning 150 skulls per frame

yes, you did, good job. can you take a moment and think about changing two things about the score display:
1) fixed width, period. the fact that the entire line of text moves move left and right on change is... not amazing UX. the only thing that should move is a changed number.
2) the color, with no outline, is difficult if not impossible to read when skulls are stuck at the top in a new level. consider moving it to the left above the hell shop.. and .. please #1.
