Hello, I am the developer of Xye. It is a coincidence because I've been planning to finally get rid of the copied sprites in the next version.
Classic and xmas are the skins that have copied sprites. default and clean look similar but are completely redrawn using Inkscape. I plan to replace the color scheme in default/clean so that it looks less like the original in the future. Meanwhile, for debian's policy it would be better to remove the following files from the package: - kye.png - kye32.png - kye32_luminosity.png - kye_luminosity.png - kye_icon.png - classic.xml - classic32.xml >From the res folder AND also every file in that folder that contains "xmas" in its name. These sprites are not needed by Xye to run. Legally the game has become abandonware PS: Python Kye (The game from moria.org.uk ) is a different clone with its own set of free sprites that does not use the original ones.
