thanks for playing and the compliments!! yes level 3, unfortunately if you go forth and back over the lever (so 2x) it will open and then close the trapdoor, and if you then go inside through the trapdoor whilst it is opening and then closing, you can get stuck there, we didn't notice that this can happen during testing (lack of time). So for the future players, walk over the lever once (then jump back over the lever) then go in that traproom to get the paper safely
