Little gnome adventure

I think I have a gamebreaking bug. The first time you encounter the human and you have to hide, the moment he leaves the door closes and the switch to open it doesn't work. Meaning I'm stuck in that room

Bug to report: there is a major bug at the very last room of the last level with the blocked door- you can walk off the edge of the room/world.

When the character respawns after this, it respawns above the ceiling outside the level. I had to rewind
