I upload your games plugin and when you click install it produces a 500 internal error. The plugin appears on the installed list but no "settings" option and no appearance anywhere on main site.
Please enter the URL of your web page to me as PM - I will try to find and fix the problem...
...yes, on my developers website plugins are cheaper...
