I think you should provide a timestamp so that what you’re saying can be confirmed or denied more easily.

Another thing I should’ve mentioned: in parts where you say the player moved without the key showing on the keyboard overlay, can you hear a key being pressed? This video has audio.

I haven't found a part of the run where the player moves without a key being pressed, but I will say that sometimes it happens if you play on, say, 60fps and you record on 30fps, especially if your recording skips frames.

I had in fact already activated the switch in the branch before I reset the game, by the way.
