Hi, Amos. Thanks for the reply.
I'm a little reluctant to mess around now as I finally got it functioning in the desired fashion by using the 'Ludum dare' link (whatever that means) and then using wordpress' link option so that I could display 'Play' instead of the link.
Are you sure the 'Widget' option wouldn't run my game in the blog post?? This isn't what I want. I want a simple 'Play' link that when pressed opens the game in full browser mode.
As I say, I got that with the Lundum dare link so I have got it working how I want, but when I was testing a few weeks ago I was definately using the embedd code and getting the option to change the link to say whatever I wanted.
Anyway, I'll try your Widget method as an experiment and get back to you.
