So you're giving up because you can't admit the 1st dimension is what it means?
Rotating 90 degrees means it's moving along 2 axes. If you rotate 90 degrees in a 2d game, it's still moving along a 2 dimensional space. You can't rotate at all in a 1D space.
Your length argument only proves mine. Length is left and right (which is the x-axis). Length is just the x-axis, width is the y-axis, and height is the z-axis. Here are images from both ChatGPT and Gemini, since you can't understand well:



Your 4D Golf argument also sucks. We can't see the w-axis. In the game, the w-axis is just represented by the y-axis. It's still the y-axis and still moving in a 3-dimensional view. If the x-axis and y-axis are swapped in a 1D game, you're still moving along the 1st dimension.
For the gravity argument, I wasn't that specific. What I meant is, gravity getting flipped in a 2D game will flip up and down or left and right. In a 1D game, the controls are flipped. If it's zero gravity, the 1D game will just be floaty.
If you wanna stop talking and take what I'm saying, that's fine. If you wanna continue giving me bad takes, that's also fine.
