After more procrastination and refining of existing code, I've added a placeholder (PSIV) menu. Yay. You can move between the menu items using the dot, but it moves too fast due to how I programmed it.
But hey, it's progress!
I've also measured how much memory my game occupies. It's taking up 1,1 MB. This is an outrage! It should take up at least 1 GB! (/sarcasm)
