Captivate Games

I want to start using games in my training.  The templates I have looked at talk about downloading a hotfix related to 2017.  Have these games been fixed for 2019?  Is there a better or worse template to use?  Also, most of my users have cell phones they use for training.

New Button Assets

I am starting to use the new button assets in Captivate 2019.  I love them but am wondering if I can change the colors?  The system lets me go through the motions but nothing changes.
