It looked very interesting, but i got stuck at the part where you have to move the mouse up/down to match the gear's speed, right at the start :/
:<Ya just gotta make it move with the other wheel and in the same directionidk what other instructions to give lol
You were probably spinning the gear the wrong way. If slow jut slow down all the way until it goes the other way and just keep gong until the task completes
