Hi, can I ask you how you got your game's cover art to look so crisp on itch.io? I'm not sure why, but mine keeps looking blurry. Even when I upload at the recommended size.
If you're speaking about the thumbnail of the game, I had to work strictly with the given dimensions of the canvas. The logo was made at a bigger size, but being mostly lasso, it is less of a problem unless the edges blur (I had to use the Sharpen option under the Filter in Clip Studio).
