This is a great pack. I wanted to use this pack in an open source game. Not really sure if the licence allows it. Game is open source so it means people can see and download the packs from a public GitHub repo. Or from inside the downloaded Game Maker Studio game. I'll put the link to this page in readme.md file.
I have some of your paid assets too but I won't include them in the open source game. I'm only talking about the free assets.
