>4th dimension is still time. 'The button' takes you to your character's view of moving across a 3rd dimensional plane. I'm assuming the two different textures on the ground represent the change in the 4th dimension (time).
No, time is actually a 5th dimension in this 4D game projection.
The developer has actually done the proper 4 to 3D projections, like he has done for the 2/3D that he shows in the beginning.
In the 2D to 3D you can definitely see that he's not moving through "time", because you can see the 3rd dimension.
The problem is just that we can't intuitively visualize a 4th spatial dimension that makes this difficult.
But he's definitely not moving through "time" or in some "past" when the "wall wasn't there". And of course moving through time has different properties than moving through a 4th spatial dimension, so it's not really comparable.
E.g if we had a gradual rise in temperature from 0oF to 100oF in the time-dimension, then if you could move through the time-axis you'd experienced different temperature at will, whereas moving through any spatial axis would you'd only feel a partial rise in temperature.
