Using Free Version of A* Pathfinding in a comercial project

Hi Aron, hope this the correct category to put this question, if not please let me know where is the correct category, im working in an ipad 2d game using your amazing A* currently using an old free version but working pretty good.
the game is schedule to be released on may 5th, so what are the steps to follow in order to use your free scripts in my comercial project ?
thanks in advance!


You are completely free to use the free version in a commercial project. However if you make money on it, it is appreciated (but not required) to purchase the pro version to support this project. A credit is also much appreciated (but not required either).
