Second playthrough. Seems like most was fixed, and I actually explored the first level more this time. Only things standing out on Map02, are missing triggers for any lift that leads down (but the triggers to return are there), and the two secret rooms right next to the exit don't seem to be accessible. https://www.youtube.com/watch?v=l3_gIf9shcs
ah no its just that you have to press enter before you get on the lift so it will work
I might make it a walkover trigger rather than switch, just so it's more intuitive
