Hey, fighters! I made a basic GDD available for public with description of how the game should work. It's a good starting point to discuss a specific features and actual game techniques. All the future details about mastery, skills e.t.c. will be written in this document. Feel free to check it and ask any questions.
Also I'm welcoming my producers and mentors to add their thoughts right into the GDD. (As fare as I understand how to allow you a rights to edit)
