I was speedrunning Red Ball 5 - Any% and I skipped Level 30 like 2 or 3 times when I was in Level 28. It took me back to the level select screen and I cannot press space 2 times. Not even my mouse. I wanted to get to Level 30 in it. But I thought Level 30 skip isn't allowed. So is it banned?

in regular any% the timing ends when you complete level 30. if you do not enter the portal at the end of level 30 the run is not valid

Oh okay.
