Yeah, I probably could have zoomed the page out to 90%, and it would have been fine. In my case, playing it at 100% in Brave (with bookmark bar enabled) was *just* enough to be too big for the browser pane on a 1920x1080 monitor in Windows.

Thanks! Sorry to hear about the canvas size. I thought that would fit most resolutions and that if anything people would only want to expand it (hence the F for full screen option). 
I just tried using the browser zoom control to reduce the size of the canvas and it worked great!

Very nicely done! A bit awkward for my window size, somehow, since the game canvas just barely exceeded the size of the page, but great sound design and the shooting and movement felt fluid.
