I've intentionally left that open, do what feels right. If it feels right to you, it'll feel right to the judges.

Yeah I hear ya. Life get's too heavy some times. All I can say, is if you have time scale back a small idea and just have fun with it. Given the time scale small scale concepts could well be all anyone has time for.

Quote: "Can I ask what Et Tu Create means and does, I would be interested in learning more about it but can't find any reference to it online except a blank website."
Et Tu Create is a production company for educational courses in america, after writing Teach Yourself Game Programming for Android and Windows I was contacted by their representative to evolve the concept into a full fledged professional app making course. The company is working with an association which means that this course will grant future students with a real world qualification. This effectively makes knowing AppGameKit Tier 1 an employable skill with companies world wide. Pretty exciting stuff right!
You likely did find the website we're using, lol. But we're working on the core learning systems right now, we'll get an entry portal set-up at some point. Because we're very nearly working directly with schools, colleges and universities however a consumer level entry portal isn't our top priority. Though again, we will get a proper site up for visitors in the future.
