Might need to refresh to lead the new version if the old one is still cached.

If the performance is really bad you can try this alt version (just a temporary alt test version before adding settings and phone support)

spwslite.netlify.app

Controls besides clicking/tapping stuff:
On PC you can zoom with mousewheel and drag around image with RMB.
Press J for something silly.
On phone you can shake the phone for the same silliness.
