The theme for the first Game Dev London Summer Jam is:

London

And when we say London we don't just mean hit us with your biggest Ben (although you of course can if you want to). Use some of these questions to guide your thinking: 
What does London mean to you?
What do you think of when you hear someone say London?
What are some images/objects/things that represent London?

Your game doesn't need to be set in London, nor necessarily include anything from London. As long as you can tell us how London inspired your game, and we can see that shining through, then you're on the right track. 

Remember, you can also enter other jams as well. Incorporate London into your game as well whatever their theme may be to apply to ours as well!

Let's get started and we'll see you in the Discord (http://discord.gg/WFck2gW) for breakfast tomorrow!
