You can complete the chamber with an easy 3 or 4 steps though lol

could you add some speed gel or something on the floor to make walking to the bridge take up less time? cuz every screw up leads to more walking.

This puzzel was a pain. after spending half an hour trying to find out what the button does (nothing) I eventually resorted to dropping the cube from the exit door into a portal than quickly replacing it so the light bridge catches the cubes forward momentum just barely enough to block the laser.

not sure if that was the intended solution but i didn't see any other ways.
