Some level fixes

I couldn't hold the mirror in the projector room in chapter 2 when the projector was turned on, but there were a few cases where I couldn't hold the mirror even if the projector wasn't turned on unintentionally. I fixed this issue.

Chapter 3 The distance where you have to jump next to the torture chamber has been shortened a bit. This is because there was a case where you could not climb while holding the edge of a certain section.

The wording of the widget describing the climb key has been changed to "Press w or the right mouse button".
