Sadly would like to have seen your site but waiting for 4 minutes for your site to download on my phone is not acceptable in my case.
Sorry to hear that
Site is not small (~3MB) but usually loading only few seconds even on phones with 3G.
Can you please let me know model of your phone and connection speed you have used? We will try reproduce and fix issue.
Actually the size of BitKong.me is 4.3mB and loading time using broadband connection is 10+ seconds.
You should optimize it.
Yes, we have background sound which is 2mb, which is gradually loading in time of gameplay, and other 800kb image, which we think to change to SVG.
We use best practices in browser caching and also we use CDN for all assets of the website, second load of the website should be around 30-40kb.
