Yes you can use the free version for any non-commercial projects if you want to sell the game later on you would have to get a full version of the pack.
Hi, I'm new to this game dev thing and I was just wondering if when there for free but for non-commercial use only, does this mean we can use it in our games but can't publish it to the appstore or playstore
that means you cannot earn money using the free version of the pack. You can still make a game and post it for everyone for free, but cant earn money with it unless you got the paid version of the pack.
