Hi I'm from Langdon School and we are making an educational game and I was wondering if you can set up a game on this website? If so, how?
No. I believe you misunderstand the purpose of the site. This is a site for asking questions and answering questions. We don't develop games on the site, host games on the site or anything like that. Get a quick overview of the site here: https://gamedev.stackexchange.com/tour
