4. Figure out how to build statically-linked Mac binary, and create a build script for packaging it.
5. ----IN PROGRESS---- Figure out how to input game mode and (if applicable) IP address and port through the GUI, instead of the command-line.
6. 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).
7. Allow the user to quit before the game actually starts i.e. while they are inputting the game mode.
