Firstly, my apologies that my editor (VS Code) took it upon itself to remove trailing spaces in levels.js:
42
The only substantive change is in line 2329 which fixes the problem with the left and right arrows not lining up in the popup at the end of each level.
In about.js there was a problem for me with the bottom ray going through the last line of text. I've moved it down so that it is now between the two ships.
