Thank you! Yes, the boiler room is the sticking point for many people, I now realize. Were you trying to jump up when the coal shoveler looked down to shovel, or when the smoke was in the air between his view and you? One player told me that he was attempting to jump up when the shoveler shoveled and couldn't get past it, and that it wasn't a difficult passage once he realized the idea was that he should jump up when the smoke was blocking the shoveler's view. If you were attempting to go up when the smoke screen was there and it still wouldn't work, then I will try to test this on more browsers and perhaps lengthen the time of the smoke screen. And thank you for the feedback on the bug on the clothes change and crouch!
