Every dollar counts! We will send you a Thank You mail and keep you informed about development and release (you can choose not to receive any mail if you so wish).
All of the above + a copy of the program (price will most likely raise after release).
All of the above + your name will be included in the special thanks area of the program.
All of the above + we will send you a copy of a very cool gamebook made by us.
All of the above + we will add a link to your website/blog inside our software, and you will get to test the release candidates during the end stage of development.
