Extra Levels
Beginner
default.kye from the original game was intended as an introduction to the game, but includes some good puzzles. There is also Beginnner.zip, from the classicgaming site for Kye, which is intended as an introduction. Play these just long enough to get the basic mechanics of the game.
Other simple level sets from the registration set are Lizzy, Lucy, Tail.
Remember that if you get stuck, just go to the Game menu and Restart Level to start over.
Intermediate
Most of the levels in Quests, Jungle and Maze are of intermediate difficulty.
From the registration levels: the first few levels of Andrew, Butter, Jasper, Jenny, Monsters, Nathan, PetesKye, Shapes, Volcano.
Kye has no facility to save games — deliberately, so that you have to get it right in one run. Each level set can contain any number of levels, and you can't jump to a later level without knowing its name (so you should remember the name of the last level you were playing, and jump to this level using Goto Level from the menu). But it's pretty easy to cheat, if you forget, or get stuck and want to skip a certain level: you can just open the .kye file in a text editor, and read the next level name out of the file.
Tough Levels
There are my other levels, plenty in the registration levels, and the levels on classicgaming. There are other Kye sites with levels linked from the Kye category on dmoz.
