Thank you for playing!
The idea behind that one tutorial prompt is that for the previous screws in that room, it's possible to get them into a usable position by just pulling them as far as they'll go, which automatically detaches you without needing the button. That one arrangement with the prompt is designed to actually force you to use the button instead, but yeah it's very much possible to just figure it out on your own without interacting with that prompt.
"Demo" kind of is a bit awkward for something that's not clearly a demo for a bigger project, yeah. I definitely would like go back and finish this, I'd really like to actually implement the other two abilities that are missing, but I don't actually have any guarantees - I mostly just couldn't think of a clearer way to phrase that text when scrambling to block off that unfinished area before submitting.
Lot of people are complaining about the head speed, I meant it to feel very deliberate to move it but ig it should be a little faster.
