there is no need as soon as you load and continue its not an IL anymore, its a segmented run.

What do you mean with segmented? As the game allows you to select the levels indivually there are 2 option. Full run of all levels in a row or each level individually(take a look at the Level leader board).

Of course not. It needs to be verfiable. As long you can provide a video (stream, youtube or download) everything is fine.

I will remove any glitched runs and will reject any new ones
