This is lovely stuff, looking forward to the next update - no rush, of course.
Two small issues to report - first, there's an empty space in Lab A7, right in front of the sink, that you can talk to and get the "Doc, I have to ask..." dialogue at any point in the game. Second, the word "through" seems to be misspelled as "trough" every time it appears in the game - you walk through a tunnel, and a trough is what farm animals drink from.
