DraStic

I'm on chapter 4, I think. There is a moment where I need to hold the cover and to pull the lever at the same time. I don't know what to do. This isn't working. When I try to pull the lever the cover falls and covers the lever. I think there is another solution, but I need screwdriver in that case. And I can't get it because the game doesn't let me to go to the second floor. What shall I do?

Sorry for my bad English. I'm not a native speaker.

Try touching the spot in between the two points. That's how a dual press registers on a real DS.
