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!
