Based on beta tester and internal feedback, we made some pretty big changes to the game (which is why there is such a long period between the beta and the release date).
We got rid of the simple ("Classic") courses because their designs were too boring, and we replaced them with new courses that are more interesting.
We added a new stick-based putting mechanic.
We also did a bunch of smaller stuff such as changing the course selection interface, making the course editor easier to use, and making course sharing more powerful and intuitive.
Thanks to the beta testers for all your feedback, and we hope you will enjoy all the changes and additions in the final product!
