I have implemented population balancing in the game. If your population exceeds the total population your houses can provide then everyone dies. And also you require gold to cast the reversing spell so if you spam it you could run out of gold. I think even after that the reversing power might be a lil too op. If I ever work on this game in future I'll definitely try to come up with a better limitation. Thank you for pointing that out. I'm glad you liked the game otherwise.
