K.O.L.M. is a remarkable little game, for a number of reasons. The graphics are odd; tiled, but with a sensibility out of Gustav Klimt, the music a curiously serene piano piece despite the (by late game) frenetic nature of the platforming action. The game does an excellent job of introducing new capabilities for your character -- starting with the conceit that you have neither legs nor eyes, initially, so that the level is blurry, and you can only flop slowly about, but adding more capacities over time. Quite often, you see something you want to get to in a level, but cannot, until you develop some new capability, and must backtrack to get it.
Initially very simple to play, difficulty ramps up slowly, with increasing challenges both in terms of enemies and platforming skill. It never reaches masocore levels, however.
The backstory, such as it is, is that you are a robot and must recover your parts. As you do, your passive-agressive mother talks with you about your progress. Story is largely irrelevant to play, of course, but the unusual, whiny nature of this interaction intersects pleasingly with the unusual graphics and music.
It's excellent, really, though the need to backtrack does become tedious at time; there is a map of the whole game that is gradually revealed as you play, so at least figuring out how to get back is not too hard. And there's a walkthrough if you like.
