You definitely have a good foundation. There's plenty of ways you could take this. Personally, I think it would be interesting if you had to occasionally leave the control room to fix something. Like the power goes out and you have to go fix the breaker box, or maybe when a certain 'entity' becomes active you have to run to and lock yourself in a panic room until it settles down, etc.
Could also introduce new 'entities', along with new mechanics to keep them contained as the days go by.
I do have one problem though: aside from the button to switch rooms, it's not very clear what the other buttons on the control panel do, and this isn't really clarified in the tutorial.
Yeah, I hear you. As this game was originally made for a week long jam, I had to cut cornes. I didn't expect anyone to play this game any more, so I moved to other projects. But since you came here and anyone playing in the future should have a 'good' experience, I'm going to clean everything up, and update this game once I have enough time.
