I would implore you to consider just posting the demo on here and letting us test it for you, since apparently your friend cannot be relied upon. With it on here, not only do you have numerous testers, but also numerous people who would be able to offer critiques and suggestions to help your work flourish. Even though I am working on my own games, I can and will make time to test yours. That shows how much I believe in your story and want to see it flourish and grow into the amazing game I know it can be. I know I’m not the only one that feels this way. The first hurdle to overcome is getting it tested. Of which we’re your best bet.
