It's probably the weakest of the unofficial "The Universe is Toast" trilogy, as it is simply a reskin of Keen 4 slightly modified with new maps, and I think that is by design. I think Ceilick is trying to ease into the more out their ideas that will be present in the other two entries. This does a really good job otherwise of establishing another planet that Mortimer McMire has taken over, and the Krodacians will be back in the 9th and final game.
