the rules read:

"Must complete the game with no mistakes at all, fixed mistakes are not allowed. Put 001 for the changing number is lesson 1."

But currently the only video on the board makes several typos in level 3 and uses backspaces to get a better score.

Is that allowed? Personally I think it should be, I'd just like some clarification on the wording.

Also could we get some clarification on the timing? The any% category timer stops at last button press, but the 100% stops at screen wipe. Which is it?

Yeah I think the wording there is pretty confusing too, I’d prefer correcting mistakes to be allowed as well.

Yes, to elaborate, generally 100% runs involve collecting 100% of some kind of point system. The only point system in this game are calculated at the end of each level and presented. As long as it shows 0 mistakes at the end of each level, it should still be considered 100%.

Think of it like playing Donkey Kong, missing a banana, and backtracking to pick it up before finishing the run. Still completed with 100% of bananas, the only penalty is time lost.

I split on screen wipe because it was easier for me to time when the screen visually went black than when I pressed ", didn't really check out the any% runs before submitting mine, my bad. Might I however suggest a "100% No Corrections" category ; )
