Sadly we overscoped and the game ended up with a bunch of features that we didn't manage to get in time and obviously no time for polishing. As such in the current version, there is the bug you encountered - The resident info table opens up - but if you click at a house while it's up, it's gonna get stuck there - and if you open up the actions menu in a building with no residents, you'd have no way of closing down the table- which will get you locked in that state- Good news is that I have already fixed this bug for the post-jam version. 

You didn't miss anything. The build and murder buttons have no effect in the current version of the game. Didn't manage to implement them in time.  We are planning for a post-jam update where all these issues are fixed, so stay tuned!

Thank you for playing and taking the time to leave a comment too! 

Yeah we sort of overscoped for the final version and I should have hidden several buttons to prevent confusion with the not yet implemented features. 
We definitely wanna get the game to be closer to our initial vision for it. I have already managed to find the bug in investigate. Fixed the issue with the resident information panel staying up indefinitely.  Made the employee select go with click instead of drag and drop. So I hope that by the time the rating period is over, we'd have an updated more complete version!
