Fixed Width for Unique stuff

I’m a Unity developer, and I’m using a plugin called UnityDog to embed the unity player easily in posts.

The size of the player is really important. Standard Unity webplayer is 960×600.

First of all that doesn’t fit comfortably inside a standard post. Second I’m unsure as to how the game reacts on other devices, but it’s not really meant to be played on phones as a web game.

Is there a way to put it in a standard post properly (right now it’s sticking out the right side). Is there a way to lock it to the proper size?

You can check it out here. I’ve put it up password protected so it won’t pop up on the site. Password is: unity.

Thanks.
