Big bug: If replaying without first closing the browser window, the game remembers you found a certain item last time and you can go straight out without needing to find it again. I use <<forget $...>> to fix this kind of thing myself. Well done since I found it interesting enough to play twice!

Tiny typo: fluorescent is spelled like the element fluorine, not like flour for baking.  Loads of people get this wrong, for some reason. You can tell I used to work in science education, right?
