Hint: your mouse is (probably) not bugged. If your problem starts on the level labelled SLIDE BACK!, try moving the mouse in the direction indicated by the arrow instead of the direction you think it should move in 😉.
Another hint: on the levels PUSH! and PUSH BACK!, the instructions do not say CLICK! or DRAG!. How could you PUSH something using your mouse cursor?
The unexpected level of difficulty in these levels is due to human error in our state-of-the-art game production factory. Rest assured that the human responsible has been disposed of.
