Hi Kisito!
Just to let you know, I've been using your new site this week and I have to say the games are great. You can see some of them in action on my facebook feed at
https://www.facebook.com/EnglishTenerife.
One minor problem I experienced in Firefox is that sometimes the images do not show up first time, but if I minimise the page and then maximise it again, there's the photo. I don't know why and I've not tried it in other browsers to compare as I only discovered the problem yesterday.
Do you have any news on the 'customizable' element yet? I have been having a think about it, and if it were possible to re-write an XML file that fed the game its questions, then that would be ideal... What do you think?
