DEVELOPER NOTES:This game uses Stage3D and requires wmode option to be set to ‘direct’. Adding this option shouldn’t cause any problems and will allow many high quality games to work on your website. This mode is set to direct by default on large flash portals, like newgrounds, for example, and is set by default here at flashgamedistribution.com.

To implement it add one line to html page:
wmode: “direct”

Example:
var params = {
menu: “false”,
scale: “noScale”,
allowFullscreen: “true”,
allowScriptAccess: “always”,
bgcolor: “”,
wmode: “direct”
};
