First, I got ED 2: Hole.
After dying, I was a bit sad to know I would have to go through the entire beginning again... but then I DIDN'T!! I love that failing is an intrinsic part of the game that propels you forward anyway.
Then I got ED 11: NO SMOKING
Whenever I look at the poster wall, it wouldn't let me leave without dying from smoking again. But after that, the issue seemed fixed and I could use the Green Door button freely.
My next endings in order:
ED 10: HELP
ED 3A: DARK
ED 6: REJECTED
ED 8: STRANGER DANGER
ED 12: REAL
ED 5: RADIATION
ED 3B: EATEN
ED 9: FALL
ED 1: ESCAPE
I love the system of pressing the buttons; it's really satisfying. The rat part made me laugh so hard.
Using the function key to move the camera up and down was really interesting too! I enjoyed the mix of 2D and 3D elements a lot! It was something new and really cool to me.
Great soundtrack, amazing sound effects as always. Floor 4 freaked me out so much that I left it early before I could die to whatever was calling to me behind the door. Absolute nightmare fuel.
