There are a couple of spots where it's possible to softlock.
First softlock situation is in MAP11 past the blue door. The bridge raised with the skull switch will end up raising too far up, blocking off passage to the switch at the end or leave you trapped inside there if you ran across the bridge as it raised.
Second one is in MAP22 at the blue door. Said door cannot be opened from inside the tiny room with the switch inside, so requires opening door, hitting switch, running out and getting past the bars.
