Sonic 3&K Angel Island (Dark) di sleepy999

I really liked this extension: <a href="https://addons.mozilla.org/en-GB/firefox/addon/sonic-3-knuckles-angel-island" rel="nofollow">https://addons.mozilla.org/en-GB/firefox/addon/sonic-3-knuckles-angel-island</a> But, the colours were too bright for me. So this extension slightly darkens the image, as well as using darker colours. Easier on your eyes!
