Hi Jeremyglebe,
Im happy you like my assets :)
I'm not familiarized with Phaser, but what the license terms mean is that you shouldn't used my assets to sell or distribute for free to other people. But you can use them to make commercial or non-commercial video games or other audiovisual projects.
Im no really sure if that answers your question, if you need to ask me more detailed information we can chat at Twitter @Krishna_Palacio
Have a good day!
