I really only cleaned up the code, added forward and backwards switches between maps with left and right arrow keys, and a zoom with spacebar. A can also be pressed multiple times to enable or disable it without having to reset the project. Also added a volume slider in the top left, where you can hover to reveal it so it isn't obnoxiously present always. If you would like to take this or edit it (like make the zoom stronger or something) that is cool with me, you don't even need to credit me
I made the zoom up to 200% so it completely fills out the screen and also shows all the numbers better
