You don't absolutely need a capture card to record your run. Some people use their phones, heck even some switch lite players have recorded their runs. I do not agree with your reasoning, but I do think level runs would be cool.

I think maybe a grouping of level runs would be a little more interesting rather than just a single level. ex: categories 1-10f. 11-20f. 21-30f. Timing ending on the first frame of the elevator of the next floor (11f, 21f) and the same ending point as ng+ for 21-30f, reticle disappearance.

Seems kind of hard to read, and the fact that you need 4 different colors for each letter... I'd be more in favor of other artsy runs, like the heart%.
