because the instructions are reversed, it doesn't tell you to hold shift then interact (which would work) it tells you to interact and THEN hold shift which i've already tested and know doesn't work. so yes the games instructions are incorrect.
"Interact to push." "Hold shift when interacting to pull." nothing tells you to interact before pressing shift, it says "hold" "shift" "interact" in that order.
"Hold shift (when/while/as you/before) interacting" is all interchangeable.
