Instead of forcing players to use private servers, you should just set the server size limit to 1 instead, so every public server acts as a private server, only that it closes instead of saves when the player exits
The premise is pretty classic. The controls and functionality is janky though. As mentioned lower the player-limit. The ramp should have borders to avoid the balls falling off. I feel that the walls should connect to eachother. The GUIs can use work as well. While at the beginning there isnt much guide on what to do.
I see, maybe you should use the whole “lobby” system like gas station simulator (except the creator of the server can choose to kick people at the lobby, and only starts the game when they press start)
Very nice game ! i think you can add music or something like that. Maybe you can add an “?” button because when i play to your game the first time, I didn’t know how to play
