Bugged... semi-soft lock if you trap yourself in a door - reset level (reset might not be possible on the last door since you can't reset the ending room but I don't know if getting just to the corridor is enough to trip the end dialogue...)
There's bugs and there are bugs... pretty sure it's not meant to soft-lock... also... can't you read tongue-in-cheek? Shame, the internet must really frustrate you...
