Sorry, but still no. Even if I offer a product for free, I still need people to acquire it from my page, under circumstances I control. They see the screenshots I choose, they see the links I choose. They improve my metrics by just visiting the page, making it more likely to show up on search queries and get suggested to others by itchio. They are in my product ecosystem, and are more likely to see and buy other products of mine. Your website is an unknown quantity. I have no idea what to expect from you or your site. You're seeking to use my art to increase your own sales, not mine. If you want to help out your followers, you can provide them a link to this page and tell them they can find some free stuff here. But they still need to get that free stuff from me, not you.

Twierdza RPG Maker Polska is not a sales website. We are an informational site about the aforementioned engine, interesting graphic resources, tutorials, and so on. Many users still use RPG Maker 2k, which is compatible with the 16x16 resolution of your works. Our editorial team is happy to inform users about interesting resources, but only if we can offer a free demo for download on the site. Well, if you don't want to expand your reach to the Polish community, we understand. Thank you for your time and I wish you good luck.
Personally, I would like to add that I bought a graphics pack for my game, and it's great.
