I created a test text to appear when the game is in the gameplay state, I made sure that the memory that has been allocated for the TextElements gets freed, and I changed the name of the MenuElement struct to TextElement because it will be used for everything that has to do with text.

Also, I added if statements in the CMakeLists.txt to separate the MacOS and Windows code, added an ifdef statement to start separating platform-specific code in the source files, cloned the project on a Windows 11 virtual machine, and linked its SSH keys to my GitHub account.

Last, but not least, I added the SDL_image library to the project as a submodule. I need to make sure that the Windows version runs fine before proceeding with anything else.
