Welcome to the lagoon, Sam. You should definitely try out my Adventure Creator program. It's free, has tutorials, and generates HTML5 code. I'm happy to answer questions, but please ask them in public so that others can see the answers and benefit from them. The thread Mimailia linked has a ton of information about the program. It's what I use when I create the erotic dating games that Phreaky and I make (some of which have been well received).
