Ah ok, thanks! I did some testing today and haven't been able to reproduce a black screen in the electrical room, but will keep at it. An issue I've been coming across is how enormously difficult it is to test every room's connection, since there are so many branching pathways, and each run takes 30+ minutes. I think next on the roadmap is to build a cheat system so I can get around the rooms faster to test specific things.
Thanks for the kind words 😄 it's my first solo game (publicly), so it means a lot!
