Pleasure. I am also one who develops games alone, but I am no so much young as you: i've not so many physical resource. My problem is that my video games do not have a great story to tell, but should induce curiosity as they are handmade. I, as you say and I have already done, always put the first level or a level that does not exist in the full version, but is compatible with the style of it and the synopsis.
