I hope so. There are a number of places where I think there could be more story threads...
The bosses lift, what if you could make it go somewhere?
When the room with two doors has lots of doors, a path which does go somewhere if you take the correct route?
Managing to stop the countdown
The glitched escape pod ending
Actually being able to complete the confusion ending as per schedule.
If you hear it's raining outside and jump out of the window will the ending change.
Listening to the recorded message could somehow cause a chain of bad things
I'm sure there are many more possibilities
Apparently you can stop the countdown, but i'm not sure if anybody has done it yet.
