This is a neat little experience (barring of course the bug with buying buildings). I think having a more clear end goal as well as player guidance could go a long way in making the player's choices feel more impactful. Sound effect feedback could also be helpful as I did not realize a flood had happened when it first happened in my run. Beyond that, I really like the very compact feeling to the graphics overall and would love to see an expanded version of this game mechanics wise. Good job!
