Keen 4 Versions
This page lists the known versions of Keen 4 and any differences discovered between the versions.
Keen 4 is special in the case that a version of the game was released for promotional purposes when the game was still a good deal away from completion. And like Keen 1, there were also a few publisher specific versions developed of this game. The actual updates to the game had some quite minor bugs fixed. The exception is version 1.1 where the bug with gems not getting properly saved was fixed, the bug which in the worst case scenario could cause you to get stuck in a level.
