Hi @Misterm,
Thanks for reaching out!
Crediting is not mandatory, and your consideration means a lot and is much appreciated. You're more than welcome to credit us via our itch.io profile link in the game credits: https://jbh-prods.itch.io/.
Alternatively, if you prefer not to credit us at all, given these assets are for commercial use, that's perfectly fine. Your satisfaction with our products is our priority.
Choose the option that works best for you. If you have any other preferences or questions, feel free to let us know.
Thank you and happy game development!
Edit: "Crediting is mandatory" became "Crediting is not mandatory" because I forgot to write "not" and I'm so so sorry about that!
