after narrowly escaping the train he finds a portal (tube behind portal) and falls through into another world huh huh the portal could be behind the train when you start level 4 for that last idea i was thinking it plunged into a ocean but after i sent the comment i rememberd that you escaped the train
i was thinking beacuse killer obects arnt very good for this kind of things and i usualy have to take of killer to stop the whole level erasing maybe you could drag a piece of paper out of the key press the leter and continue the ragdoll could have weak hinges but overall great idea love the scenes and plead for level 6
