I agree! While programm is not completed and periodically changes, Wiki is a good tempory alternative.
But in the future, we all would like to see completed program (at least the major part) with full manual.
I understand that writing help is boring and difficult stuff, but i think it's very important part of success. What is the meaning of helicopter, if nobody knows how to fly? .. If you want to promote your program and make it popular, as soon as there would be stable version, you should seek to make your prog available and understandable as for advanced game developers as beginners. Besides Construct is based on "click & play" system, and to create games is more easily than using engines with difficult scripts.
If gamecreation and learning the program would be simple and fascinating process, many people will come.. and for this you really need full and well-organized manual. Learning program using tutorials is good, but it's more suitable for advanced users.. for example, to see full process of creation small game. But if you're beginner and even don't know interface, buttons and where everything is..? All we need to learn from the simple to more complex things.
There're not so many people in our country who can buy expensive programs and engines, so people prefer to learn free soft. There're many free programs and people prefer to learn more "easy to understand" program that has a lot of info, documentation, tutorials, etc.. If it hasn't normal help, people stop learning program and look for another one.
Your program is very cool, absolutely free and so it has all chances to become very popular (especially during the world crisis )! It is good solution for low-budget game studios and new game developers.
So... I very much hope that the situation will change with new stable 1.0 version .
