Any project use is fine, whether it's in a game engine, or print media even. I've had some people say they wanted to make a tabletop game and use the images and that is fine.

Nice, that sounds excellent. Thank you very much for your quick answer. I have started to publish my WordPress site (https://4ce2be.wordpress.com/) for Indie Devs in Germany and would like to use 2-3 of your wonderful pixel-arts on the front page. Of course, I will also refer to you, and I can also link to this itch.io if you like ;)
Your work really inspired me the most in the asset packs, great work!
