Hi drdevel0per,
Thank you for contacting me, I have checked the game just now on Steam and sadly the dev didn't credit my name, instead by using other name. It's true the license said that it is allowed to use in personal or commercial projects but I forgot to mention about credibility using my name in any projects. I guess this is entirely my fault, I will write a better license document next time. This is very helpful and learning experience, thank you so much for sharing this information drdevel0per and supported me by purchasing the asset pack.
I will upload a new asset pack soon and still working on the product page design, so stay tuned!
