Hi, thank you for taking the time to write a thorough review :)
We did indeed lack the time to implement proper feedback (mostly, sound feedback). We planned to have signs that lamp sockets were empty/broken/about-to-break, as well as properly showing how the switchboard was the way of reparing broken sockets. Also signaling when a door has been open would have been great but we ran out of time sooo fast T_T
We may update the game with sound effects and more feedbacks once the jam is over though :)
