There are some tutorials posted on the official website of the developers. You will have to use those, because there are no manuals or additional resources. The website is using some sort of Adobe Flash for their menus and I can't post the direct link to the tutorials page, but you can simply visit their website through the link below and then click on the Tutorials button on the upper-left side, then access the tutorials.
Note: Make sure to enable Adobe Flash in your browser in order to load the website, else you will get an empty page.
