Quality of life and testing

Lobby

Added map selection (Right now my test map and High rise map with test course)
Added selector for the number of laps needed to finish the map

General

Technically now the game is playable in multiplayer, but it’s complicated to connect with your friends, because it works only on LAN and might need opening ports in your firewall
You now have a specific way to go through the rings (I need to implement a visualization for which one is the next for you), only the one you should go through next will activate and add to your score
You might need to complete multiple laps of the same course when you set it up in the aforementioned lobby slider
