Do people influence how fast the tower goes?
Playing tower control you have to stand on a tower to get into the enemy base. Some people stay on the tower and the other go forward and splat people. When someone else is on the tower I usually go forth and splat people. But if there are more people on the tower will the tower go faster?
After looking at the inkpedia page on tower control, it says that
The tower no longer gains a general speed boost from having multiple Inklings ride it. Instead, the number of Inklings only affects the speed that checkpoints are beaten.
