1. Add 'install' target to Meson, to allow the user to install the game. This should also copy the .so files to the right locations.
2. Use the struct to establish a connection, and to start each round (instead of sending strings).
3. Figure out how to build statically-linked Mac binary, and create a build script for packaging it.
4. Communicate the paddle reset position to the peer, after a round.
5. Clean up / refactor the raygui code in main.cpp, that asks user for game mode. Instead of just having a giant blob of code in main.cpp, maybe split it into a function, or move it to another file. It should be easy to split it into a different function, since none of the functions take any specific parameters. The text box function, for example, only takes in the rectangle coordinates, and the text to display. I can move the code to a function, and then pass in any parameters that I need to pass in (I don't think I need to pass many parameters, though).
6. Allow the user to specify which paddle they want to control, in multi-player mode.
7. Try to make the ball go between screens.
8. Change the networking code, so that a single server can connect two clients with each other. The server should provide player 1 with a code, and player 2 can connect with player 1 using that code (essentially like a room).
9. Create (or find) an icon for the application.
10. [This can't really be fixed, since I'd need to purchase a developer certificate] Sign Windows executable, to remove 'Unknown Publisher' warnings.
