It's simply set way too high and it destroyed a lot of fine detail (especially hair) and made outlines fuzzy. It's especially visible in high-color images, where chroma subsampling really takes its toll.
I don't know if there's any chance of it, but I'd love it if you offered a separate download with compression dialed back.
That, I believe, was a necessity, to make possible for everybody to download the game. Without the compression the game would have been to big. I guess Tlaero can explain it better than I and also pronounce on the separate dowload without compression.

yahoo wasn't speaking of the compression used to make the zip file for downloading. He's talking about the jpeg image files themselves. The .jpg file format is one that allows the same dimensionally sized image, in this case 1250x625, to be saved using different compression ratios. Basically, you could open any .jpg into an image editing program and re-save the exact same file and make it take up less disk space without shrinking the image. To do this, some of the image information must be discarded. Most images can be saved at 80-95% (which means that some of the information is changed) without any real noticeable difference to the average human eye (think of it like taking 2 slightly different shades of blue and saying, you know what, let's call these identical and just use 1 shade of blue).
That wasn't really a technical explanation of how it works, but hopefully it gives you kind of an idea of what is happening. If you want a slightly more in depth explanation (once again this is just a generic representation. Actual algorithms are more complicated then this)... you have a file with the following information:
"abababxyxyxy" original file = 12 characters in the file
"3ab3xy" zip file = 6 characters in the file (the zip file knows that numbers mean how many times to repeat what follows)
"aaaaaaxxxxxx" jpg with compression = it decided that
a and
b are close enough to equal and
x and
y are too, so got rid of the duplicates.
"6a6x" new zip file = 4 characters total
The zip files are completely reversible. You can uncompress "3ab3xy" and you will get exactly "abababxyxyxy".
The jpg compression is not reversible. Once you've gone to "aaaaaaxxxxxx", you have lost information. There is no way to go back to the original.

I don't know anything about how Mortze is actually doing his rendering, but my impression wasn't one of an overly compressed set of images. To me it appeared as a stylistic choice. His images generally appeared softer and glossy, maybe a bit more anime-ish. Either way, I'd be rather surprised if he was creating larger images and shrinking them down to distribute. (Don't get me wrong, the style may be being generated during rendering by high compression... but it still felt like an intentional style choice.)
