well, I went ahead and basically blindly went to the next screen.
the text disappeared then, okay.
Played it till the screen after the phantom.
killed phantom, went through the right exit.
Upon being spawned on the next screen,
I thought "Why not go back a room"?
well, so went back through the left door which should lead back to the phantom room.
however another room with swinging platforms is shown and I seem to get spawned
somewhere in the void where I basically insta-die.
So I see this empty screen with the swinging platforms, cant see my character anywhere and his health jsut instadrains to zero before coming back to full over and over again :-)
