It's tough for me to even play because I can't see the whole screen at once. Even if I change the zoom inside my browser, it shrinks the area for the game canvas, but the actual stuff inside the game canvas doesn't get scaled down proportionally so stuff just gets cut off the sides. That seems to be something inherent to Godot because I just went back and looked at my game and it does the same thing. Elements that are positioned by control nodes do actually reposition like you would expect them to, but the entire game doesn't scale like you would expect. So I'd probably recommend setting up your project settings / display / window to have something small like 800 width x 600 height so it'll fit on pretty much any modern screen without needing to mess with browser zoom.
