Haha! When I first played Nightclub Showdown I thought to myself "huh, this has neat mechanics, it'd be nice if someone fleshed it out".
Later I have actually started (and still am) working on my own game that was very inspired by this. I thought that some game jam game burried on itch.io was too niche for someone else to take as inspiration, and that I was at least somewhat original. WELL, I've been proven wrong!
Congratulations on this, it is funny to be surprised by someone having basically the exact same idea. Although my concept for the game was somewhat different.
