A lot of people have been emailing me asking how to install the package. Since it isn't from the asset store, the process may be slightly different. The kit comes with full documentation, but you have to import the package before you can access that. I figure I should post this in the forum thread as it may help others who may have the same question.
Once you have imported playmaker into your project, simply import either the "PlaymakerFlappyBirdKit.unitypackage" or "PlaymakerFlappyFishKit.unitypackage" into the same project. Then navigate to the scenes folder and load a scene. Make sure you read the documentation that gets extracted into your project as well.
In case you are not aware, you can double click a unitypackage and it will open in unity. Otherwise you can right click in project view and choose "Import Package / Custom Package," then navigate to the unity package you wish to import.
Cheers guys, I hope you are enjoying the kit!
