Isn't this mistimed by a few seconds? I'm pretty sure timing ends when the curser disappears, not when the button is pressed. Though I'm not sure what reasons there are to having the timer stop at the white flash instead. But that's what the message on Discord said.

I think I figured it out.

You have to enter the launcher from the bottom side.

I did something weird in the first chamber, causing me to not go through the hole. Heres a video.

Pretty sure its faster this way, not the way I did it, but I think you can see how it could be faster

So for anyone who was wondering if you can just rely on blind luck to have the cube land on the button, you cant, there is like, an invisible force that pushes the cube away from the button
