Subsequently, Kye has been reproduced for platforms other than Windows 3.x. This has been from scratch since the original coding is not available. Python Kye reproduces the behaviour of the original game very closely, including some behaviour that was probably unintended by the original author. It comes with its own level editor and uses level files in the same format as the original game. Xye is a version written for modern Windows which has some departures from the original behaviour and introduces some entirely new elements; it also has its own level editor and uses a different level file format, although it can read files of the original format (though Xye omits the ability to move diagonally, so levels that rely on this are not playable).
