Was having fun. Completed all but the scientist objective as I couldn't find the last person. I found what looked to be a hidden location and as the person there said "Hello" it crashed the page. oof.
Happy to find out it remembered my progress. And I found the final delivery and completed the game. And yes, I'm sure the girl on the roof is a 'hidden' thing. She talks about three.js, game development, and art.
SPOILERS AHEAD (for another game, which you should have played by now, if you enjoy this game, in my opinion) There's also a hiss at the industrial site which reminds me of the game Full Throttle where you have to kick the wall at the right time. But that can't be a thing, right? But the gauge!
