when i use f12 i get this error btw : failed to load resource: the server responded with a status of 404 () index.js:1 Failed to load resource: the server responded with a status of 404 () (index):102 Uncaught ReferenceError: Engine is not defined at (index):102:16
also engine is defined in index.js which isn’t able to load

edit: i also posted a screenshot showing the source , and index.js is there but doesn’t work somehow
I have a public folder with index.js and other pngs needed to run web build , index.html file is in root , the public folder stuff get cloned to dist folder when running npm run build and should work normally but they don’t work , here’s my index.html script :
<!DOCTYPE html> two can stick html, body, #canvas { margin: 0; padding: 0; border: 0; } body { color: white; background-color: black; overflow: hidden; touch-action: none; } #canvas { display: block; } #canvas:focus { outline: none; } #status, #status-splash, #status-progress { position: absolute; left: 0; right: 0;
} #status, #status-splash { top: 0; bottom: 0; } #status { background-color: #242424; display: flex; flex-direction: column; justify-content: center; align-items: center; visibility: hidden; } #status-splash { max-height: 100%; max-width: 100%; margin: auto; } #status-progress, #status-notice { display: none; } #status-progress { bottom: 10%; width: 50%; margin: 0 auto; } #status-notice { background-color: #5b3943; border-radius: 0.5rem; border: 1px solid #9b3943; color: #e0e0e0; font-family: ‘Noto Sans’, ‘Droid Sans’, Arial, sans-serif; line-height: 1.3; margin: 0 2rem; overflow: hidden; padding: 1rem; text-align: center; z-index: 1; }
