Description

Mystery City is a game series created by my cousin and I in 2013. Development ended in 2016 and we both moved on from Roblox, but we are still so happy to see people playing our games and enjoying them so much. We never expected to have such a successful game and have awesome memories of our time on Roblox interacting with this amazing community. Joey (Ptah70) has left Roblox permanently, but I (Zack aka Mario5422) do check here every month or so to respond to messages! Thank you for all of the love & support :) Q: Why is the game not working correctly? A: Due to updates to Roblox's engine, we've heard that several aspects of our games are no longer working as intended, unfortunately. There is at least one account that has completely remade the games to be compatible with modern day Roblox, though! Their username is MCRemake :)

2 measurements spanning 4 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 618–619 and does not start at zero.
