The python bejeweled clone "Monsterz" lacks a .desktop entry... I'm not the hottest at reading ebuilds and I didn't check the source to see if a desktop file exists, but I did take a few minutes to write one... The .desktop file I wrote uses an absolute path to "/usr/share/games/monsterz/graphics/icon.png" for the icon, properly the icon should be copied to an XDG-recognized dir so the .desktop file doesn't require a full path. I also don't do translations, cheers!
