I've tried looking for hints to get through the Mines, I know I need the Robohand to get to the end, but a Youtube video showed that the user already had the hand before the start of the level. If I didn't get the hand on a previous level, can I get it here, or will I have to start over or skip the level?

EDIT:Nevermind, I cheated to get all the keys at once in the previous level, and it turns out because I did that, I missed the Robohand and was unable to finish this level because of that.
