Oh, interesting! I thought you were using C++ going by the code snippets you had showed here every now and then! But I think it makes sense when you're working on a big project such as a game all by yourself and there's no one else to port it for another platform (or a base engine which already compiles for different systems), you can have more time working on the game itself instead of having to tinker with how creating a graphical window differs on Windows from X11 and so on.
