cool!
Alright, I was able to find out why the game kinda ran slow. It is because of my browser settings, I used to use Chrome then Firefox and then Brave and recently switched to Opera GX. I have set almost everything in Opera GX to low and have disabled hardware acceleration. This hardware acceleration has to be turned on for the best experience of playing my game in the web because well the generated web files are in JS, HTML and Web Assembly. Web assembly directly uses your computer if I recall correctly and having hardware acceleration off causes the game to run slow.
