Thank you for your reply, any feedback is welcomed no matter how harsh, especially criticism, as long as the intention is good.
I can assure you that what I already have cannot be done in one month, even if one would have worked full time on it. The reason it took so long (almost a year) is that first I had a prototype built with another game engine, 2D, which is btw now open source, you can pick it up from here
http://vortexarena.sourceforge.net/, and only the last 6 months have been spent by working on the game, while also learning Unity. Maybe I don't show that in my video, but there is a beginning for everything, and I am still learning to make presentations:). Most of the game content randomly generated each time, and all those algorithms can take a lot to develop, especially when you need to generate 3D content out of them.
Unfortunately I don't have enough time to spend on presentation videos and also work on the game but hopefully people interested in spending their money will also visit my website and see all the progress that has been made in other screenshots and videos that are not available on the campaign website.
I have also made an assumption that people would be more willing to invest in stuff that goes into the game directly or improves its quality (like music and better technology), and know that none of that money would go into my pocket for my work on the game. The game itself will be completed anyway, it is just about its final quality that depends on funds I do not have.
